Erel,
I downloaded Beta edition, install with no problem.Run for the first time with no issues. Open Designer with no problems but it stated that for better perfomance to download and install Net Framework 4.5.2
Download and install NET FM 4.5.2 after that, b$a never starts again. Just a windows message that B4A has stopped working.
I do not have any further debug info as it does never launch.
If you tell me how to gather more info on the crash I will post it here.
Was simpler than that.
When you install B4A Beta, it install by default to the same v4.30 directory, although it ask for new desktop icons, if it founds the shortcut exists on the desktop, it does not overwrite it, leading the desktop icon pointing to Basic4android.exe and not to b4a.exe.
That was all, now working as a charm. Keep you posted if I found any bugs.
