When you install a program that uses the InstallShield program, you may receive the following error message:

This issue may be caused by any program that installs different versions of the Oleaut32.dll, Olepro32.dll, Asycfilt.dll, and Stdole2.tlb files (and possibly others). This may create a mixed file version environment with files that are not compatible with each other.

To resolve this issue, use the appropriate method.
