Try an older version.
11.50 will not work.
I used B4A 7.80 on 32bit Athlon XP 2600 with Windows XP (Service pack 3) single processor and 1GB of ram, this is the latest version that work on 32bit machines, newer versions just will not work.
I used it until last week, now I got a new PC x64 because I need the latest releases as I have to prepare my apps to be published on Google Play Store.
It should work on your machine but you are limited.
But as
@DonManfred said:
Using an old version of B4A is a waste of time. Your apps will fail on new devices.
Latest B4A 11.80 will work even on a 100-150 EUR x64 Celeron machine and you are not limited.
Good luck.
