Is it possible to do a custom install of QAS 4 and only install the MMC snapins without installing the QAS Control Center?
Currently you have to install all items.
You can remove the QAS Control Center by deleting the file C:\Program Files\Quest Software\Authentication Services\QAS Control Center.exe, after the install.
To remove the Group Policy snapins you can unregister the GroupPolicyExtensions.dll file.
regsvr32 /u "C:\Program Files\Quest Software\Authentication Services\x86\GroupPolicyExtensions.dll"
