When attempting to activate Microsoft Office 2010 receive error
"An unspecified error has occurred. Your request cannot be processed at this time.
Please try again later. (0x80070190)"
This is another instance of UAC interfering where it does not make sense.
Enter the key as you would normally do so.
Then you have two options Simple and Complicated , both work
Option 1 Simple
After update , Simply start any Microsoft Office 2010 application , Word , Excel etc.
with Administrator privelges & then activate.
You only need to do this once to activate
Option 2: Complicated
Open a command prompt with Administrative privelege.
Navigate to one of the following folders.
Win 7 32 bit
C:\Program Files\Microsoft Office\Office14
Win 7 64 bit with 32 bit Office
C:\Program Files (x86)\Microsoft Office\Office14
Run the following command
C:>cscript ospp.vbs /act
You should see something similar to the following.
C:\Program Files (x86)\Microsoft Office\Office14>cscript ospp.vbs /act
