Pressing the Red Button

I couldn’t run the latest Silverlight because an older beta version was installed. I kept getting an error during the install process that vaguely suggested removing the old version. So I went to Add/Remove Programs and I got an error when trying to remove it. After some research I found some instructions on how to manually remove it and reinstall. This worked for me. Below is a summary of the steps:

1) Download and install the Windows Installer CleanUp Utility. Find Microsoft Silverlight in the list and Remove it.

2) Use Regedit to remove the following Silverlight registry key:
HKLM\Software\Microsoft\Silverlight

3) Remove the Program Files\Microsoft Silverlight directory (be sure to close all your browsers first or your directory will be locked.)

That should do it now you can go back to the SilverLight web site and redo the install.
