B4X:

cd C:\
dir /s /b B4A.exe

Beware, it's slow as HELL because it searches the whole C:\ drive.

Thank you!
Maybe if we know where to search in the Registry... @Erel?

You can narrow down the search if you suspect it will be in the Program Files (x86) or the Program Files folders. Those searches will be a lot quicker. You can also test all the drive letters to see if they contain a Program Files (x86) or Program Files folder. There's a bit you can do to streamline this.

I found that the following key [HKEY_LOCAL_MACHINE\SOFTWARE\Classes\B4A Source Code\Shell\Open\Command] contains the B4A location.
I hope it's common to all B4A installations...

the fastest would be this

B4X:

reg query "HKCR\B4A Source Code\DefaultIcon"

and parse the result

B4X:

HKEY_CLASSES_ROOT\B4A Source Code\DefaultIcon
    (standaard)    REG_SZ    C:\Program Files\Anywhere Software\Basic4android\B4A.exe,0

I don't know if B4J supports regRead if not you can call the above which doesn't require an additional file or use an addition batch/vbscript file.
