I can't seem to get secondary logon service to run, it is not listed in services.msc and i have tried to cahnge the value to the correct one in the registry but i can't seem to get it working. This is what happens when i try to use 'Run as' on a .exe file: And this is what happens when i try to install postgres, which is what i really need to do: Any help would be greatly appreciated. Cheers
