I am running ROMSHELF on a 64 bit OS by keeping the directory stored in my program files(x86). When I have entered in all the directories for the emulator and rom list I hit the "regenerate rom list" button and/or the "save settings" button and nothing happens in either instance. I have seen videos of people using romshelf and it immediately brings up a text box with how many roms were found, but when I try it doesn't work. Is this because I am using a 64 bit version of windows 7? It seems to operate fine until i try and regenerate the rom list.
