No, SLIC is there, it works fine. Both Server2016 and Win7 showed as activated. But for some reason I wasn't able to update from Win7 to Win10, like it usually works. In the error log it says the "PidGenx function failed on this product key". Not sure why. I also installed a new bought Win7 Pro key on a clean system (worked fine), but it also failed to upgrade to Win10 in the same way. I'm guessing SLIC 2.1 would not help, there is something else not quite right with my system.... First time I'm dealing with an X570 board, maybe that has something to do with it. Normally I stay away from Win10, but this one is for a friend. Anyways, thanks for your help!

Thank you! I'll give it a shot! Edit: Same result. Thanks for the help! I'll just go with a cheap ebay key this time.
