The following table lists the known compatibility fixes for all Windows operating systems that have been released from Windows Vista through Windows 10.

You will receive an error message if you try to use the wrong version.
You must use the 32-bit version for 32-bit applications and the 64-bit version to work for 64-bit applications. The Application Compatibility Toolkit (ACT) installs a 32-bit and a 64-bit version of the Compatibility Administrator.
