Hi jimski000,

The steps below might help you.

Step 1:

Uninstall SilverLight from Control Panel.

Refer: Uninstalling previous versions of Silverlight from Windows

Step 2:

Delete the “Microsoft Silverlight” directory from under Program Files.

ü From an administrator command shell on an x86 you can do this by running:
rmdir /s /q "%ProgramFiles%\Microsoft Silverlight

ü If you are on a 64-bit version of Windows, substitute ProgramFiles(x86):
rmdir /s /q "%ProgramFiles(x86)%\Microsoft Silverlight

Here’s how you do it.

a.    Go to Start and type cmd.
b.    Right-Click on cmd and select “Run as administrator”.
c.    Type the above command whichever is applicable for your version and then press Enter.

Step 3:

As with many uninstallations, this may not delete Silverlight entirely.
In particular, it will probably leave behind some registry entries.
You can remove them from the registry by following these methods.

Important: This section, method, or task contains steps that tell you how to modify the registry.
However, serious problems might occur if you modify the registry incorrectly.
Therefore, make sure that you follow these
steps carefully.
For added protection, back up the registry before you modify it.
Then, you can restore the registry if a problem occurs.
For more information about how to back up and restore the registry, click the windows help article below.

Back up the registry
http://windows.microsoft.com/en-us/windows7/Back-up-the-registry

c.    Navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight]
d.    Delete Silverlight key.
e.    Close registry editor

Step 4:

Install Silverlight by downloading from: http://www.microsoft.com/getsilverlight/Get-Started/Install/Default.aspx

That should be it.

Manually editing the Windows registry

Manually editing the Windows registry to remove invalid MACHINE_CHECK_EXCEPTION keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely!

Caution: Unless you an advanced PC user, we DO NOT recommend editing the Windows registry manually. Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows. We do not guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

To manually repair your Windows registry, first you need to create a backup by exporting a portion of the registry related to MACHINE_CHECK_EXCEPTION (eg. Windows Operating System):

Click the Start button.
Type "command" in the search box... DO NOT hit ENTER yet!
While holding CTRL-Shift on your keyboard, hit ENTER.
You will be prompted with a permission dialog box.
Click Yes.
A black box will open with a blinking cursor.
Type "regedit" and hit ENTER.
In the Registry Editor, select the Error 0x9C-related key (eg. Windows Operating System) you want to back up.
From the File menu, choose Export.
In the Save In list, select the folder where you want to save the Windows Operating System backup key.
In the File Name box, type a name for your backup file, such as "Windows Operating System Backup".
In the Export Range box, be sure that "Selected branch" is selected.
Click Save.
The file is then saved with a .reg file extension.
You now have a backup of your MACHINE_CHECK_EXCEPTION-related registry entry.
