None of the ideas you gave worked, but thanks anyway. It resolved on its own, and if you encounter this issue, the solution is simply to wait — it gets fixed after 24 hours.
I was expecting to get a single exe file as a result of compiling.
BAS gives a folder with several files as result of compile operation. You can zip it and send to customer. In fact that folder conatins only online installer, which will download correct BAS version with correct architecture on first run.
