Hi, we can try to find your previous key. Are you remember your email, which you used for the Parallels Desktop 4 registration?Hi Maria,
Same issue here......I have upgraded from a very old version of Parallels Desktop (V4) to V15Pro and it is not working (as it asks for the V15Pro key then the older key but it doesn't work) that old license is on an old machine and the machine is dead and can't be used.
Can you help me link these versions please OR can I get a refund for the Upgrade V15Pro license no. 199223988?
Is the only way to buy a new Full V15Pro license to get working?
Thanks Mark
