    There’s an MSDN post that reports the same problem, with a solution:

    So I went to HKCR\CLSID{A8F03BE3-EDB7-4972-821F-AF6F8EA34884}\InprocServer32(Default) in my x64 environment, and saw the following path: C:\Windows\system32\mscoree.dll.

    Customer changed the C:\WINDOWS\SysWOW64\mscoree.dll path he found in there to the right one, and he didn’t get the error again.

    There’s no explanation given for why the path might be wrong, but it seems it worked… you could at least check that registry setting and see whether it looks wrong on the box in question.
