Sometime Cornell's licensing for MS Office doesn't "take". Here are ways to fix that problem.

CIT has a documented solution

Oliver's successful effort using a different and seemingly similar solution

10/2016, on Art's (Freed group) old laptop (ACERT, INC000001786822)

Solved licensing problem by rearming and (re-)activating license, per:

• http://texhex.blogspot.com/2015/03/office-2013-kms-activation-system.html

Steps taken

(Step 0) Optional: Run cscript ospp.vbs /dstatus

• C:\Program Files (x86)\Microsoft Office\Office15>cscript ospp.vbs /dstatus

I used this to confirm that "GVGXT" matched ending for "Office 2013 Professional Plus":

(Step 1) Run /rearm command:

• C:\Program Files (x86)\Microsoft Office\Office15>cscript ospp.vbs /rearm

(Step 2) Run /act command:

• C:\Program Files (x86)\Microsoft Office\Office15>cscript ospp.vbs /act

Confirm success

Quit MS Word. Re-launch and confirm all good: File => Account.
