Hi bltllc,
"Is this something I need to even worry about?"
The Office Genuine Advantage Validation tool will Validate your currently installed copy of Office and inform you if it is Genuine or Non-Genuine.
However, if you are having troubles installing the tool, you can instead, go to
http://microsoft.com/genuine and click the Validate Office button. This will also Validate your currently installed copy of Office and inform you if it is Genuine or Non-Genuine.
Since a customer would need to activly come to Microsoft to use the Validate Office button, we intended the Validation tool to be released thru Windows Update as a 'We come to you' Validation process instead of the user having to 'Come to us' to Validate.
Hope that answered your question,
Darin MS
