I am trying to run a batch file in Windows 8. When I unzipped the tool I am trying to use, the batch file turned up associated as a PDF, which was useless. I managed to change the association to Notepad, so now I can read it, but it will not run. In previous versions of windows. the association would be "windows bat file" and I would just click and run. But now I can't get it to run. Help please!
