No, those are 2 rather old installations of LOL on Linux in wine. Both were upgraded +/- about the same time to "new client", because there was no option to continue playing "old client". One system works, other does not. It's all in comment #5: https://bugs.winehq.org/show_bug.cgi?id=42584#c5 .
So I thought, I could just copy working installation over to other system where LOL didn't work in the hope that it might work, which did not help. So I ruled out "bad upgrade".
Ok then. But did you copy whole .wine directory or just the game directory? I just wonder if the game has broken someway with wine (wine upgrade or something similar).
