I purchased and installed parallels pro 10 for mac a few months ago and a new win7 install with my oem key from old pc. Parallels popped up a window saying to install new version and I did and now win7 says my key is invalid. How do I fix this?
That didnt fix....its telling me "Windows is not Genuine" and pops a window to buy one from MS....was workign fine....now also getting a lot of blue screen crashes. All was good till upgraded to v11, can I revert back to 10? if so how?
