Trouble Installing Modern Warfare 2

[wolf18]

I don't really know where this post belongs, so if there is somewhere else I should post it, please let me know.

I am running Windows XP and I was trying to install Modern Warfare 2. I click install, but after a while an error message comes up that says "This application or DLL C:/windows/Microsoft.NET/Framework/v.1.1.4322/mscorwks.dll is not a valid Windows image. Please check this against your installation diskette." What the heck is going on and how can I fix this? I was looking about related problems and their solutions and there was everything from removing Trojan Horses to uninstalling Windows. What can I do to fix this?

Nevermind. I fixed this. I put my OS disk in and reinstalled NET Framework again. I think that I was just a bad file. It started installing now. Hopefully there won't be any more problems.
