Here the solution to an annoying problem that took me some time to track down. I’m posting the problem and the solution to help any other fellow sufferers there may be out there.
I have a brand new ThinkPad running 64-bit Vista. But when I tried to install Microsoft Office 2007, no joy – it would copy the files from DVD then stall until I cancelled it. Same thing happened with Office updates. When I tried to install the Java Development Kit (JDK), I got an error message saying that another install process was running and that had to complete first.
After much pain, I finally tracked this down to the Brother XP spl Service (BrSplService – brsvc01a.exe), installed with the software for my Brother MFC 420CN. I still have no idea what this does, but I did find a patch for the problem on the Brother site. Problem solved.
