Hi!
First of all, we're very sorry for the inconvenience caused by the unsupported winvers.
I can assure you we're working on the fix - MesaChanger v2. It will not only add support for the newer versions, but also a ton of new features.
I'd love to give you an ETA for it, but there simply isn't one in order not to rush anything. Sorry.
If you want to use Mesa right now, you need to downgrade your Windows version. If you want a guide on how to do that, feel free to open a ticket on this website (in the Support tab) or ask on our Discord server.
Have a great day!
