Hello, I have copied the VM from my MBP to my new iMac and installed a fresh Parallels Desktop application. When entering my upgrade key to version 4 and then my license key for the 3 version I got the message that the upgrade key is wrong. Q) how do I disactivate my license for the MBP and make it free to use for the iMac ? I searched on my personal acount page but I can't find such an option. BTW, the installation is succesful, with a fresh trial key Parallels and the VM are working fine so the issue is narrowed to the transfer of the license keys of version 3 and 4. Thanks for any help, Wim
Problem is solved It turned out that for the second key I used an *upgrade* key from v2 to v3 instead of an older permanent key. When I used an older permanent key the license was excepted. In line with the license terms I removed the app + VM from the MBP. Wim
