I have installed a Unity 4.0(5) server for a customer, I tried opening the Unity Diagnostic tool but received an error message from MMC informing me that the Snap-In failed to initialize. I should have seen all the common diagnostic tools and the logos but I just get a blank screen.
If I open MMC on its own and then browse to the UnityDiagnostics.msc file I also recieve the same error, however if I open other *.msc files they appear to open ok.
Has anyone else come across this issue before? Everything else with the Unity server is running ok.
