Now with Windows 11 I had to reinstall B4X. I've had to do this several times with a new computer. This causes problems every time. Files keep appearing to be missing. The downloaded zip files are not extracted properly, not even with 7-zip. If others also have this experience, here's a tip: don't be discouraged, unzip several times until all the necessary files can be installed in B4X. It is time consuming and annoying, but then you have something. It would be nice if you could install B4X in one go, with Java and all resources.
