I bought the Bentley Manuel dvd/cd from eBay years back.  Turned out that to transfer the license it had to be deactivated from one computer to activate it on another.  The guy on eBay was just a seller so he had no idea what pc it was ever activated on.  So I contacted Bentley publishers and after several emails to them and getting the  “we don’t care”. And an agreement that said the manual could not be transferred. I actually found the original software agreement on the disc. Which said it was fully transferable as long as you show proof of purchase.  Sent the original agreement to them along with if you don’t fix this legal action will be taken….An hour later I had a new serial number and an activation. What a hassle though just to get something that was legitimate purchase. If you’re in the same situation I would suggest look at the original agreement on the disc.
