Hi, Originally I bought the physical box of Parallels 3.0 a few years ago. A couple of month ago I bought a copy of Parallels 4.0 (not upgrade but full version). I sold the box of Parallels 3.0 and appears as "Invalid Installation Key". I also installed in my computer to test it, and appears the same. Has my key expired? Where can I find my key again? Regards,
Are you sure that the 3.0 was a full version and not an upgrade. If it was an upgrade from 2.5, you first have to enter the 2.5 key and then it will ask for the 3.0 key.
Yes. I bought a box with Parallels 3.0 It did not include version 2.5. The strange thing is that the CD envelope has 2 keys. None of those work. Do I need to try installing 2.5 before 3.0?
We suggest you to submit support request for Online Store department and provide the scan of your CD envelope with the keys: http://www.parallels.com/support/request/
