When I double click the CGminer launcher it opens and closes so fast I can't see where the error is in the bat file.
Instead of double-clicking the batch file, open a command prompt (cmd) and navigate to the batch file and run it. It will keep the window open so that you can read the error messages.
For example, navigate to D:\Some Folder\Miners\cgminer-3.7.2
Then write myfile.bat (whatever your batch file name is)
