When a setup is launched, the following error message occurs:

Error number: 0x80070725
Description: Incompatible version of the RPC stub

This error 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.
