The error 'Incompatible version of the RPC stub' is caused by an incompatible version of a DLL that was installed on the system, such as Oleaut32.dll, Olepro32.dll, Asycfilt.dll, Stdole2.tlb. For example, version 3.50 of Oleaut32.dll is installed and used only by Windows XP and so causes this error if it is installed on a machine running any other operating system. Ignore the error message: "A required .DLL file, C:\windows\system\oleaut32.dll, was not found." This error message appears because the file was renamed in step 4 .
