Some software applications are installing incompatible versions of Ole32.dll and Comcat.dll, causing errors with other software applications such as ArcInfo.
For ArcInfo 8.0.1 and 8.0.2
After installing ArcInfo 8.0.1 or 8.0.2, if you get DLL registration errors after reboot, followed by a runtime error, you may have mismatched versions of Ole32.dll and Comcat.dll.
This error will also cause the following problems upon trying to start the applications (e.g. ArcMap or ArcCatalog):
Microsoft Visual C++ Runtime Library - Runtime Error! Program: C:\arcexe80\bin\ArcMap.exe abnormal program termination
For ArcGIS 8.1
If the files are incompatible when you install, you'll receive a message. If you install something after ArcGIS 8.1 that updates either incorrectly, you may encounter the following error upon trying to start the applications (e.g. ArcMap or ArcCatalog):
Microsoft Visual C++ Runtime Library - Runtime Error! Program: c:\arcgis\arcexe81\bin\ArcMap.exe abnormal program termination
