We had an employee who had a broken installation of Office 2010 Pro Plus. We use Microsoft Online Services (now called Office 365) and in particular we use their E3 plan for most of our employees.

 

Simply doing a …

cd "%ProgramFiles(x86)%\Microsoft Office\Office14\"

dir *.vbs (you're looking for the OSPP.VBS file.)

cscript ospp.vbs /dstatus
(will show you something like this)

Can show you whether or not you’ve got a problem. If you do, you can reactivate the Office subscription if yours shows —NOTIFICATIONS— for its license status by going into directory…

C:\Users\faileduser>cd "C:\Program Files (x86)\Common Files\microsoft shared\OFFICE14"

and running

osaui.exe /K or /F

via cmd with either /K to do a password reset or /F to change users or reset the subscription back to basics. You can also do a /r if you need to remove another device which is using your current subscription.

Here’s a couple of links:
