Downloading the compatui.dll file
We don't advise to download the compatui.dll file and copy it to the Windows system directory. The software's creators almost never circulate the DLL files, they are always part of an installation set. It's the installation set's task to perform the sufficient verifications before the installation. An incorrectly installed DLL file may cause the system's complete inability to function.
If you need a DLL file in spite of the above for the sake of restoring a system, then download it from a reliable source, possibly from the manufacturer's site.
