cparsley #1 Posted August 30, 2012 on all previous versions of windows the programs (Stella/NesterJ/Nostalgia) worked fine, but now on a Windows7 machine it comes up saying it's not a valid program file. Error message Atari\Stella.exe is not a valid Win32 application. Driving me insane here! Quote Share this post Link to post Share on other sites
