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:

  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.

  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.
10.4

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.

Fix Silverlight in Safari or Firefox on a Mac

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.)
