I don't know how this worked, but deleting msxml4.dll out of the SysWOW64 folder, then putting another copy of msxml4.dll, then restoring the original one from Recycle Bin fixed the problem.
The only problem I have now is that I cannot install updates for it from Windows Update. I get error code 643.

Hello Caleb,

You might see if this may be able to help with this error for .NET Framework issues. Be sure to use the part for Windows 7.

Error codes

Hope this helps,

I tried what you told me to try, but Windows Update gave me the same error again

Did you also try the "Fix it" there as well?

Yes.

In that case, give OPTION TWO a try in the tutorial below to reset Windows Update to see if that may help.

I got the error again

The only other thing I know of is to give a system restore a try using a restore point (if available) dated before you had this issue.

I am system restoring back to April 13 because that is the only resotre point that I have that may have been before this issue occured.

The system restore brought back the original problem I had. Time to fix it again and maybe Windows update will work.

You should never delete/replace portions of an install. It's better to just un-install, re-boot then install. You can sometimes right click on the program and select Repair from the Programs and Features screen.
