That's it. Just the bat file. No config file. I tried to keep it simple to get rid of any other possibilities.
Ok i changed some small things, try
"this".
It's X11, the stock btc address is still in the .conf file, change that if you don't want to mine for someone else

Just tested it over here and works fine. Scan with Virustotal first before you run it. Never trust anyone here

Good luck!
I'll have to work on this one. I'll see if I can set up a test machine or figure out how to install display drivers in a virtualbox environment. Can you PM me the changes that were made?
