Uninstalling MSI Setup can corrupt Windows

There's a bug in the way InstallShield extracts COM data that can corrupt the operating system when your "Basic MSI" or "InstallScript MSI" setup is uninstalled. Read how Christopher Painter lost TCP/IP settings on his computer because of this problem. This can happen if you use the "COM extract at build" option for a component.

A hotfix for InstallShield 2008 is available but Christopher reports that InstallShield 12 is affected by the same problem. There's no information about previous versions. Macrovision knowledge base article Q113345 also includes instructions for a manual workaround that should work for any versions of InstallShield.
