    If you face difficulties while installing, uninstalling or re-installing Silverlight, or even after installing it, Microsoft Silverlight does not work as expected, then this post is sure to help you. Before you start you may want to find out a few things!

    Do I have Silverlight installed?

    You can type Silverlight in Start Screen search. If it is installed you will see it as a search results. You can also fire up your browser and check in the add ons or plugins section.

    Which version of Silverlight is installed?

    The Silverlight runtime does not offer a simple way to find the full Silverlight version number of the installed plugin from JavaScript. It only offers a way to detect if the installed version is “at least” a particular version. But you can visit this website to find out which version of Silverlight, your computer has installed.

    Website keeps asking me to install Silverlight

    If some website keeps asking you install Silverlight or update to its latest version, even if you have already done so, then open your browsers add ons or plugins manager and check if Silverlight is Enabled. If it is already Enabled, then maybe you do have a corrupted Silverlight installation, and you may need to reinstall Silverlight.

    Clean Corrupted Silverlight Installation

    If you cannot or are unable to uninstall or install Silverlight due to a corrupted Silverlight installation, this Microsoft Fix It will solve the failed installation problem. This Fix It will basically delete and clean up all the residual registry keys as well as files and folders, which were created by the Silverlight application during its installation, but which were not delete even after uninstalling it via the Control Panel.

    Download this Microsoft Fix It to clean corrupted Silverlight installation in Windows 8 or Windows 7. Run the downloaded file and click on next to follow the wizard.

    If any issues are found it will list them and offer to fix them automatically. If no Silverlight installation is detected on your computer, it will offer to download and install it for you.

    Hope this helps!

    UPDATE.

    If this does not help, KB2608523 suggests you do the following to manually uninstall the Silverlight installation:

    Copy-paste the following in Notepad and save it as UninstallSilverlight.cmd.

    Run this .cmd file as administrator. One the process is completed, run it again as administrator. Restart computer and see if it has helped you.

Because Microsoft will be discontinuing support for Silverlight, the Silverlight version of Navigator Web is being phased out. All CTI Navigator users should use Web II(HTML version) unless there is a specific need to temporarily use Navigator Web Silverlight (such as to import and convert Matchmakers from Desktop Navigator into Navigator Web format). However, until Microsoft stops Silverlight services, Navigator Web Silverlight will continue to run.

General Steps to Fix Silverlight

Silverlight is a browser plug-in (also called an add-on or add-in). If Silverlight does not install (or repeatedly prompts to install), or does not run properly in your browser (displaying either a System Exception error, an error 4001, a blank page, or a blank frame without the menu items in Navigator Web), progressively implement each of the following steps until the problem is resolved:

Install
  1. Install Silverlight in a browser that supports plug-ins:
    • To install Silverlight in Windows 10, open Microsoft Edge browser, enter the address of CTI Navigator Web for your MLS, click the 'More Actions' icon at the top right of Edge toolbar, and select 'Open with Internet Explorer.'
    • To install Silverlight in Internet Explorer on Windows 8 and 8.1, IE must be open in Desktop Mode.
  2. Verify that Silverlight is installed (see below).
  3. Ensure that the Silverlight plug-in is enabled in the browser ( Internet Explorer, Firefox, or Opera) or through a browser extension (such as IE Tab in Chrome).
    • On a Mac, also ensure Silverlight is unrestricted when running in Safari on the website for your MLS , or is Activated on the current web page when running in Firefox.
  4. Clear temporary Internet browsing files (see instructions to clear browsing History, Data, or Cache for your browser at 'Fix Internet Browser Issues')
  5. Close all browser screens. Then re-start the browser and open the website for CTI Navigator Web first
  6. In Internet Explorer* 11, 10, or 9:
    • select Tools in the browser menu and un-check 'ActiveX Filtering' (for more information see 'About ActiveX Filtering' by Microsoft) - or
    • click the Toolsicon , select Safety, andun-check 'ActiveX Filtering'.
  7. For all Windows browsers, select Internet Options in the Windows Control Panel. (If Control Panel is set to 'Category View', first select “Network and Internet” then select Internet Options.) In Internet Explorer you can select Internet Options under Tools or Tools icon. Then, on the Internet Options screen in the Control Panel or IE:
    • select Connections tab > LAN Settings button > Un-check 'Automatically Detect Settings'; and
    • select Advanced tab > under Accelerated Graphics, either check 'Use software rendering instead of GPU rendering' if it is not checked (or un-check it if it is already checked and update the driver for your graphics card), OR click here to run Microsoft's Fix-It utlity > restart the computer for changes to take effect.
    • Set Internet Explorer to Compatibility View
  8. In Firefox, set Preferences to use software acceleration for graphics (i.e., not use hardware acceleration):
    • click Options under Tools or the menu icon, and select Advanced in the left menu
    • under the General tab, un-check “Use hardware acceleration when available.”
  9. In Chrome or Firefox, install the IE Tab extension appropriate for your browser, and enable the IE Tab extension when running CTI Navigator Web.

  10. For continuing Internet security updates in Windows XP and Vista, run Silverlight in the Opera browser (rather than Internet Explorer or Chrome which no longer issue security updates for versions of Windows no longer supported by Microsoft).

  11. Close the browser with the problem, and open Navigator Web in a different browser.

If Silverlight is installed, enabled, and the browser's temporary Internet browsing files have been completely cleared, but Silverlight does not work properly in any browser on this computer, Un-install Silverlight and then install the latest version. If uninstalling and reinstalling Silverlight does not resolve the problem, see the 'Clean Corrupted Silverlight Installation in Windows ' or 'Fix Silverlight in Mac' section below as appropriate.

If Silverlight runs correctly in one browser but not correctly in another browser on your computer, the non-supporting browser itself may need to be reset, restored, un-installed and re-installed, or replaced by an earlier version. For instructions on managing browsers, see 'Fix Internet Browser Issues' in the Related Articles at the end of this web page.

Verify Silverlight Version Installed

To verify the version of Silverlight installed on a computer, click here (or go to http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx). At this website Microsoft also provides install and uninstall instructions, and a chart of compatible operating systems and browsers for the version of Silverlight installed on your computer. If your installed version is earlier than the 'current' (latest) version, you can click on the 'Current version' number to install it on your computer if desired.

To verify the version of Silverlight installed on a Mac, you can click Help and select 'Installed Plug-ins' in the Safari browser menu. Then scroll down to view the Silverlight Plug-in information.

Install Silverlight

Download Microsoft's latest Silverlight browser plug-in at 'Download Microsoft Silverlight' (or select the desired version under Download Selected Version of Silverlight in the Related Articles at the end of this web page) using the method appropriate for your Internet browser and computer operating system. The basic installation steps are:

  • To install in Internet Explorer in Windows: Click Save (or Run) to download the Silverlight.exe installation file, and then click Open or Run to install the downloaded file.
    • In Windows 10, open the Microsoft Edge browser, enter the URL address of CTI Navigator Web for your MLS, click the 'More Actions' icon (3 dot ellipsis symbol) at the top right of the Edge browser toolbar, and select 'Open with Internet Explorer'.
    • In Windows 8 and 8.1 Internet Explorer must be open in 'Desktop Mode' with address bar and controls at the top of the screen rather than in Tiles Mode with address bar and controls at the bottom of the screen (click here for more information).
    • Version 5.1 of Silverlight has a Windows 64-bit component that is compatible with 64-bit Internet Explorer (see below).
    • Earlier versions of Silverlight (4 and below) are compatible only with Internet browsers running in (32-bit) mode (such as Internet Explorer, Chrome, Safari and Firefox). To check IE's mode. either click on the gear icon in the upper-right corner of your browser screen and choose 'About Internet Explorer'; or hold down Alt+H and then press A. To run the standard (32-bit) version of IE in 64-bit Windows, click Start and select 'Internet Explorer' -- instead of 'Internet Explorer (64-bit)'.
  • To install in Internet Explorer in 64-bit Windows: Click here to download the Silverlight_x86.exe installation file, and then click Run/Open to install the downloaded file. This installs Silverlight version 5 with its 64-bit component.
  • To install in Mozilla Firefox or inOperain Windows:Save Silverlight.exe to your computer, and then select Open to start the installation.
  • To install in Google Chrome in Windows:Save Silverlight.exe to your computer, and then select Open to install. To run Silverlight, you must also install anIE Tab extension to Chrome.
  • To install in Mac OSX:Save File 'Silverlight.dmg' to your computer (typically your Downloads folder), and then double-click on 'Silverlight.pkg' to start the installation.
    • If Silverlight does not download in your Mac, set the computer's System Preferences for 'Security & Privacy' to 'Allow apps to download from the Mac App Store AND Identified Developers' rather than only from the 'Mac App Store' as described here.
  • Chrome in Mac no longer supports plug-ins such as Silverlight on a Mac.

Note: Some security programs (such as STOPzilla, VIPRE and Webroot) need to be temporarily disabled to allow Silverlight to install properly.

Enable Silverlight

Normally add-ons/plug-ins such as Silverlight are automatically enabled when installed. However, they can be disabled manually, by other programs, or by browser updates.

Internet Explorer (IE). To ensure that Silverlight is installed and enabled to run in Internet Explorer (8and later):

  1. Open Internet Explorer
  2. Select Tools in the menu bar (or the gear icon in the top of the browser)
  3. Select 'Manage Add-ons'
  4. Under 'Add-on Types', select 'Toolbars and Extensions'
  5. Under 'Show', select 'All add-ons'
  6. Browse down to the Microsoft Corporation section, and select 'Microsoft Silverlight'
  7. Verify or click the Enable button

Note: For continuing Internet security updates in Windows XP and Vista, run Silverlight in the Opera browser (rather than Internet Explorer or Chrome which no longer issue security updates for versions of Windows no longer supported by Microsoft).

Safari. To ensure that Silverlight is installed and enabled to run in Safari (6.0 and earlier):

Mac
  1. Open Safari
  2. Click Help and select 'Installed Plugins' in the top menu of the browser
  3. Scroll down to see 'Silverlight plug-in'
  4. Close Help
  5. Open Preferences
    • In Mac: click Safari in the top menu and then select Preferences
    • In Windows: click Edit or Settings, and then select Preferences
  6. Select Security
  7. Beside Internet plug-ins, check 'Allow all other Plug-ins' or see Safari Plug-in Manager below
  8. Click Close.

Safari Plug-in Manager in Mac (OS X)

To provide an extra level of security, Safari automatically sandboxes (see sandbox note below)all plug-ins (such as Adobe Flash and Microsoft Silverlight) to limit their access to key system resources. However, Safari (6.1 and later) includes a plug-in manager that allows users to set the level of security to be enforced for specific plug-ins, either on a per website basis (such as just for the website where CTI Navigator Web runs for your MLS) or globally (for all other websites).

To set Safari to allow the Silverlight plug-in to run in unrestricted mode specifically on CTI’s website for your MLS (which is needed to support CTI Navigator Web functions performed in the browser on your computer):

  1. Open Safari to the CTI Navigator Web sign-in page for your MLS
  2. Install Silverlightif it is not already installed
  3. Click on the word 'Safari' in the top left menu (next to the Apple icon) and select Preferences (click to see image)
  4. Select the Security tab
  5. Beside Internet plug-ins (click for image):
    • Check 'Allow Plug-ins'
    • Click on the 'Plug-in Settings' (or'Website Settings') button
  6. Click on Silverlight in the list of available plug-ins on the left.
  7. On the right, select the CTI Navigator website address for your MLS.
  8. To give Silverlight unrestricted access to computer resources when running at the CTI Navigator website for your MLS:
    • In Safari 10, hold down the Option key andclick the button to the right of Navigator's web address. Then check 'On' andun-check 'Run in Safe Mode' (which is equivalent to 'run in unsafe mode') in the Permissions selection box
       (click on image to enlarge)
    • In Safari 9 and earlier, click the button to the right of Navigator's web address, and click both 'Allow Always' and click 'Run in Unsafe Mode' in the Permissions selection box
      (click on image to enlarge)
    • See permissions note belowfor description of other options for other websites
  9. Beside “When visiting Other sites” (click to see image), select 'Ask'.
    • Do not select 'On', 'Allow' or “Allow Always” unless you intend for all websites to be allowed to use the selected plug-in (which is not necessary for CTI Navigator)
    • Do notun-select 'Run in Safe mode' or select “Run in Unsafe Mode” for other websites because you might inadvertently visit some other (non-CTI) website that injects malicious code or malware through plug-ins.
  10. Click Done.
    • Click the Trust button when you are prompted to trust the CTI Navigator website for your MLS to run Silverlight in unsafe mode. This will change the website setting button to display or 'Allow Always ' with a warning symbol (a triangle around an exclamation mark). This triangle symbol must be included in the setting beside 'On' or beside 'Allow Always' for Silverlight to run without restrictions. If the triangle is missing, repeat step 2 above.

    • On some Macs, you also need to select the Advanced tab under Security and un-check “Stop plug-ins to save power” beside Internet Plug-ins.

    • Reload the webpage in Safari (click View > Reload Page); or close all open Safari screens and re-open Safari so these changes take effect.

System Exception Error: if Silverlight cannot access needed computing resources (such as extra working memory), CTI Navigator Web functions may fail and display a 'System Exception error' message. System Exception errors may or may not be fatal. Other Navigator Web functions may continue to operate correctly, and the failed function may recover if needed resources become unblocked or become available (such as by closing other browser screens or apps to free up working memory). However, to avoid System Exception error interruptions, always set Safari's Preferences to run Silverlight in Un-safe mode (as described above).

Sandbox Note. Sandboxing is a security mechanism to tightly restrict access to computer memory, operating system resources, and user files for unknown or untrusted code or unknown or untrusted websites.

Permissions Options:

  • Ask: temporarily blocks a plug-in from loading and running in the sandbox until you click on the “blocked” notification and select On or Allow for this instance
  • On or Allow: allows only the most current version of the plug-in to load into the browserand run (restricted) in the sandbox
  • Allow Always: allows any version of the plug-in to load (including older versions which may be compromised) and run in the sandbox
  • Off or Block: always prevents the plug-in from loading
  • Run in UnsafeMode: allows the plug-in to run with full computer resource access, without any sandbox restrictions
  • Trust: allows a plug-in to run in unsafe mode, which can access your personal data and documents.

Note that third-party plug-in managers (such as ClickToPlugin) may interfere with or override settings in Safari’s plug-in manager.

According to Microsoft, the minimum requirements for a Mac to run Silverlight 4+ are Intel-based 1.83 GHz (or higher) processor, running Apple's OS X Tiger (version 10.4.11+ or later) operating system with at least 512-MB of RAM, and a current version of the Safari or Firefox browser (click 'Download Microsoft Silverlight' or select in the Related Articlesat the end of this web page). Silverlight 5+ requires OS X Leopard 10.5.7+ or later.

If your Mac is running 'Mavericks' OS X 10.9or later, follow the steps to use Safari Plug-in Manager (above)to allow the Silverlight plug-in to run in unrestricted mode specifically on CTI’s website for your MLS. For Firefox on your Mac, ensure that Silverlight is installed, enabled, and activated for the current web page.

For steps to fix Silverlight in older (non-Intel processor) Mac Power-PCs, click 'Silverlight for Mac is not being recognized or you are continually prompted to install'. To determine the version of your Apple OS and its processor, click on the Apple icon in the top menu and select 'About This Mac.'

Otherwise, to try fixing Silverlight problems in Safari yourself (see note 3 disclaimer below), progressively implement each of the following steps until the problem is resolved. For Firefox, follow just steps 1, 7 and 8. (Chrome does not support Silverlight on a Mac.)

  1. Close all your browser screens (Safari and any other browsers) to clear temporary files.
    • Re-open your browser and use it to verify which version of Silverlight is installed either by clicking on the 'Verify Installed Version of Silverlight' link, or
      • in Safari: verify that Silverlight is recognized as installed by selecting Help > 'Installed Plug-ins'
      • in Firefox: verify the version and status of Silverlight by selecting Tools > Add-ons > Plugins and ensure it is set to 'Always Activate'.
      • in Chrome: type 'chrome://plugins' in the browser URL/Search omnibox, scroll to Silverlight, verify or click 'Enable'; and also check 'Always allow'
    • Un-install any version of Silverlight earlier than version 4 (i.e., uninstall version 1, 2 or 3 if listed).
      • Note. While version 5 is the current version and is normally preferred, if it is not working correctly in your browser after completing steps 1 - 4, you may try uninstalling and replacing it with version 4 if that version is still available. (See 'Uninstall Silverlight on Apple Mac' above, or step 4 below.)
    • Re-open your browser and try to log into CTI Navigator Web again.
  2. Open the CTI Navigator Web sign-in page in Safari and set Safari to run Silverlight without restrictions at this specific website (see Safari Plug-in Manager on Mac above, or the summary below):
    • Click the word Safari in the browser's top menu, select Preferences... and then the Security tab (or hold down the Command key and press the comma key)
    • Verify 'Enable JavaScript' is checked, 'Block pop-up windows' is not checked (under the Edit menu in older versions of Safari), and Allow Plug-ins' (or Enable plug-ins) is checked
    • Beside 'Internet plug-ins' check 'Allow Plug-ins', and then click the 'Website Settings...' button
    • On the left pane, click on Silverlight, and on the right pane, select the CTI Navigator website address you are using for your MLS
    • Click the button to the right of that address and select 'Run in Unsafe Mode' {meaning without restrictions}
    • Click Done, and when prompted, click the button to Trust the CTI Navigator website to run Silverlight in unsafe mode.
    • Close all Safari screens and then re-open the CTI Navigator Web sign-in page in Safari.
  3. Remove Cookies and other website data (which may contain past errors) in Safari:
    • Click the word Safari in the browser's top menu and select Preferences...
    • In Safari 7 and later select the Privacy tab
    • Either click the 'Remove All Website Data' button, or, to select and remove data for a specific website , click the Details button, select the specific website (such as ctimls.com), and click the Remove button
    • Close Safari and then re-open the browser.
  4. Reset Safari to its original defaults by clicking Safari in the browser menu, selecting 'Reset Safari..'. (click here for details), and un-check any items you do not wish to remove.

  5. If the Silverlight error persists, un-installSilverlight (see un-install details above or summary below):

    • Close all browser screens
    • Open Finder and browse to the hard drive where Silverlight is installed
    • Select/Open Library > select/open Internet Plug-ins
    • Click on the Silverlight.plugin and drag to Trash
    • If displayed, also click on 'WPFe.plugin' and drag to Trash
    • Empty Trash! (You may need to restart your computer to ensure that all file components are removed.)

    Uninstall note: It’s very important that all Silverlight components are completely removed from your computer. If you encounter difficulty uninstalling Silverlight on a Mac, you might run a free Mac app removal utility such as FreeMacSoft's AppCleaner (see Download Free AppCleaner for Mac in the Related Articles at the end of this web page),and delete the appropriate installed components found by the app removal utility. Otherwise, contact a Mac specialist either at Apple (phone 800-275-2273) or the national Tech Helpline for your state Association of Realtors (407-587-1450 for FAR members and 877-573-5611 for GAR members).

  6. Re-install Silverlight (see 'Install Silverlight in Mac' above). Then try to log into CTI Navigator Web again.
  7. If Safari on your computer still will not support the Silverlight plug-in, download, install and enable a current version of Mozilla Firefox and activate Silverlight for the curent web page (in Windows but not Mac, install and enableGoogle Chrome).
  8. If Firefox or its extensions do not function properly, follow the steps described in the MozillaZine article 'Refresh Firefox - Reset add-ons and Settings'; and if necessary, 'Standard Diagnositic - Firefox'.
