Today I'm trying to deactivate the Solidworks 2020 SP0 on my work PC, then trying to get it activated on my home PC so that I can do some homework. Unfortunately the deactivation is failing. The strange issue here is Solidworks says the product is deactivated on the work PC, yet throws an error. And... Solidworks stays running on the work PC, I can do everything, but if you dare go to check out the license, then SW will close because the license is partially deactivated. 

It's great big mess, the only thing I can do is activate it fully on the work PC, but deactivation is not working today.
