--- Comment #10 from Jason Edmeades us@edmeades.me.uk 2013-01-13 17:58:45 CST --- FYI I am looking through this at the moment, although I'm not quite sure what I am supposed to be running. In the root dir is installed a batch program which does call the addpath one you list below which shows a number of problems with wine, so I am focussing on getting those going. Note you will also need a findstr.exe from windows for now to get this going even when I've fixed the cmd issues I can see.
Can you please raise a separate bug for this issue
start "xxx" /B file.bat fails
I cant see who should be setting the python path you refer to although its not my priority at the moment as I can see enough bugs to be getting on with. I'll get those into the product and get you to retest!
