According to the documentation at http://support.microsoft.com/kb/194801 , the module may not load because of security settings: Using the Windows Explorer, select Properties for the file c:\windows\system32\vbscript.dll, select the Security tab, and grant "everyone" at least read access to the DLL. This should eliminate any security restrictions that may be affecting the creation of the COM object. Security can be tightened after it is determined that this was the problem. Keep in mind, many of the dependant DLLs are Windows system DLLs and will have at least "everyone read" access already.
