Microsoft Video Screensaver Won't Install - Windows XP

When I try to install Microsoft Video Screensaver, it tells me I need to validate Windows. When I click "Continue," it opens up a link in IE and runs a script to test my Windows XP copy's validity. It then tells me my Windows copy is genuine, and redirects me to a page with MSE and IE available to download.

Meanwhile, the Microsoft Video Screensaver installer stops and says "Installation was interrupted before Microsoft Video Screensaver could be installed. You need to restart the installer."

I have tried multiple ways to get my Windows validated to work with the installer (it IS genuine), but nothing works (WGAPluginInstall, the WIndows Genuine Advantage Plugin for Firefox fails to install with error code 0x80070003).

What do I do?

I think the Installation was interrupted error comes from Windows Installer. You may have to update your system.

You can try to install Windows Installer v4.5 and then restart your PC. You will also need DirectX runtimes and .NET Framework v1.

Try again to install Video Screensaver. If you still get errors, try to create an install log:

msiexec /i <path to msi file> /l*vx C:\SomeDirectory\SomeFilename.log
