So,
i tested a lot of things.
I made a clone of my old system on an external drive and testetd it on my old and my new pc.
I can start the win10 from the ext drive without any problems on both pc's. But the Aion-Client wil not start on the new one. It's the same as above.
So i install a new Win10, download and install all needed files. On my old pc i can start with that. Also Aion starts very well,
On my new hardware win 10 starts, but the aion-client will not start...
I tried GAmeZ Aion, that uses also Active anticheat. On my old pc i can start it, on my new not.
With Beyond Aion i have no problem on both pc's.
It is not win 11 that makes the problem. I think, it's the active Anticheat that will not run with Ryzen 9, GTX 3080 or whatever.
