I installed B4J V 7.0 and B4A V 8.80 on Linux Ubuntu 18.04 Mate under wine.
B4J runs with no problems. B4A requires a License file which I copied from the Win 10 partition. There is an error:
Licence file is invalid (older version).
I purchased B4A some years ago. Probably that it was no problem to install new releases over an old registered version. May be if I install then B4A NEW with V 8.80 the old Licence file can not work?. I contated support@basic4ppc.com. I can post their answer.
