Search the registry using the reg command: ------------------ DOS session ------------- C:\WINDOWS>reg query "hkcu\software\Pytho" Error: The system was unable to find the specified registry key or value C:\WINDOWS>reg query "hkcu\software\Python" ! REG.EXE VERSION 3.0 HKEY_CURRENT_USER\software\Python C:\WINDOWS> --------------------------------------------- Next question - How to detect that you got a result other than an error? Use ERRORLEVEL ERRORLEVEL will return 0 if the last command had no errors or an error number otherwise. Thus something like: @ECHO OFF reg query "hkcu\software\Python" if ERRORLEVEL 1 GOTO NOPYTHON python myscrip.py ... GOTO :EOF :NOPYTHON REM use dos commands here > P.S. I do realise this is a little off topic... It does involve > Python > and programming... just not programming in Python. Seems relevant to me... BUT if you can be sure Windows Host Scripting is installed ands active that is much much easier to use...
