Fought with Microsoft for an hour and a half because Office 2011 wouldn't activate on my oldest daughter's Macbook Pro after the Apple store replaced her crashed hard drive Friday afternoon.
Fortunately she had the AppleCare extended warranty and a recent time machine backup, and any critical files between backups were on Dropbox or Google Drive and a thumb drive. The Apple store had it up and running for free by closing time. But after the Time Machine restore MS Office told her that it was activated on too many computers (3 license version for students, one for each kid).
We tried the phone activation twice, feeding the automated activation line the 54 digit installation ID, and then having the voice on the other end thank us for contacting Microsoft and then disconnecting the call without further notice, and no confirmation ID needed to activate Office.
The first Microsoft tech I spoke to (daughter was at work and couldn't call them) stated that Office 2011 treats any new hard drive as a new computer, and to activate Office 2011 on her new hard drive I'd have to pay $40 for another license.
I told him that made no sense because in 2012 I backed up her old computer before I wiped it, and installed her clone onto her new Macbook Pro, and Office didn't complain about the changes. I told him I did the same thing with the other 2 kids computer upgrades in 2013 and 2014, with no issues. But now he's telling me that "the new hard drive counts as a 4th computer" and he would not budge to activate Office. WTF?
The dipshit put me on hold for almost half an hour when I asked for his supervisor, knowing I'd eventually hang up so I couldn't complain and get him in trouble. I had to call Microsoft back, but the next tech was very nice and gave us a confirmation ID right away so we could activate Office again.
Meanwhile my daughter spent the hour and a half freaking out over it, with an important paper due soon that she couldn't work on during her free time at work. Maybe I should have paid the $40 right away and saved her the misery of not knowing if we'd get Office fixed, but it was the principle of the thing that made me continue to fight for our current license to work.
