In Windows, when Acrobat Reader is installed, AcrobatInfo.exe is registered as a COM server. It is registered with the wrong path : C:\Program Files\Adobe\Acrobat DC\AcrobatInfo.exe. The correct path is C:\Program Files\Adobe\Acrobat DC\Acrobat\AcrobatInfo.exe. This has been a longstanding issue that I have seen reported by CCleaner for years.
