with the purchase of office 2007 a free upgrade to Office 2010 for military personnel was offered.  Upgrade was executed and worked fine for several years. Recently, cannot verify license message is popping up.  Since the upgrade was a download (have Office 2007 disks), what can be done to restore Office 2010?

Hi,

If you purchased a product key to activate Office, please visit this link below to download a copy of Office 2007 or Office 2010:

As you mentioned it was a free upgrade from Office 2007 to Office 2010, this may be related to your local policy, I think the best approach is your local customer service for this question:
