  • deleting the mprs file and rebooting
  • clearing browser caches

I have the following version of Silverlight:

Hello Neil,

Thank you for providing a detailed information on your issue. I appreciate the step-by-step troubleshooting and the pains you took to resolve your issue. However, there are a few more steps that we can try to diagnose the root cause before re-freshing  your Windows.

Try the steps provided below and see if it helps.

Method 1

There may be broken components in a previous installation, try uninstalling Silverlight components first. There is a KB article that includes a Fix it to uninstall Silverlight, give this a try.

How to clean a corrupted Silverlight installation and then reinstall Silverlight

Method 2

I would suggest you to disable security software temporarily, perform clean boot on your computer and then try to install Silverlight again and check if it helps.

Step 1

Try to disable security software temporarily and then see if it helps.

NoteAntivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Step 2

Perform clean boot.

Putting your system in Clean Boot state helps in identifying if any third party applications or startup items are causing the issue. You need to follow the steps from the article mentioned below to perform a Clean Boot.

How to perform a clean boot in Windows

Note: Refer "How to reset the computer to start normally after clean boot troubleshooting" to reset the computer to start as normal after troubleshooting.

Step 3

Now after disabling security software and performing clean boot try to install Silverlight once again from either of the link provided below.

Get Microsoft Silverlight
