Rather annoying issue that I am facing at the moment with one of our Terminal servers.

When you try to run an install process or uninstall process it will stall at the "Gathering required information".

MSIEXEC.exe runs up at %100 CPU this process is run by SYSTEM
a second instance of MSIEXEC.exe sits there (run by current user) not doing anything (I suspect this is normal though)

I have tried the following:

installed the latest version of Windows Installer - still same issue
ran SFC /scannow - still same issue
deregistered msiexec and copied back the files (msi.dll, msiexec.exe, msihnd.dll, msimsg.dll, msinfo32.dll, msinfo32.exe) - still same issue


I am starting to run out of options for this, has anyone had this issue before or seen something like it?

Any help or suggestions are welcome!
