If this was a PC I'd just use ProduKey or some such utility.
Sadly the software did not give me the Office 2011 PID.I downloaded Office from an online store.Inside the Microsoft Office for Mac manual.The 25 digit product key is on a yellow sticker on the inside of the DVD case.Try logging into the site where you purchased Office to check your order details.Note that these solutions will likely be to check those places in the list above.A new key can be generated only if you have retail copy of the software (DVD) or downloaded version through Digital River or Microsoft Store.It's possible that the licensing plist file is corrupted.The last thing you want to do is to make a mess of how Office works on your Mac system.
I know for a fact that it worked for the "Home and Student Version".
An email from either Microsoft or Digital River that contains the code (if you purchased from Microsoft Online Store).Reply With", 01:24 PM #2, the product key isn't kept in any visible way for you to get access.Or search your inbox for an email from @m.I swapped drives so at least it works.Either way, you may find yourself needing to uninstall then reinstall Office for Mac using that key code, which is all well and good unless you have lost or discarded.He purchased Office 2011 a few years ago but cannot find the box that contains the key.I even paid the 10 for the IOS version.
This is understandable, as in the wrong hands, this app could be used the voice season 5 episode 24 to recover 100's of keys to software protected by volume licensing, potentially wrecking havoc on daily business functions in your organization.
