I’ve had the above error message a bunch of times while
trying to activate Office 2010, I’ve been able to work around the problem by
using the telephone activation option provided by Microsoft but it’s a pain and
takes about 5 minutes. I honestly can’t believe I’ve put up with problem for so
long when the solution to my problem was fairly obvious and straight forward.
If you are dealing with this error try running the
activation as Administrator (right click Word or Excel and select Run as
Administrator)
Worked first time for me.
