I am trying to activate a copy of Visio 2010 as I had to reinstall after my laptop crashed. The Visio licence belongs to my employer and my laptop is my work laptop. I have followed the instructions above but get the following when trying to activate:

C:\WINDOWS\system32>cscript "c:\Program Files (x86)\Microsoft Office\Office14\OS
PP.VBS" /act

Hi Don

I have solved the problem by locating a Visio 2010 Professional specific binary.
