Batch files are not exe's, so start.exe probably isn't the appropriate thing to execute them with. They are DOS/command prompt scripts, analogous to bash scripts. They are text files with a list of command prompt commands. Fortunately, WINE has its own command prompt. Try using that. Go to terminal, and type in "wine cmd.exe". Now you should be in the WINE cmd shell. Try and get it to run the batch file. Cheers, Jake
