I have an application which runs fine under 32-bit XP and W7 virtual machines, but throws errors when being launched on a (fresh) 64-bit W7 install. The manufacturer insists that it works properly on "real" 64-bit systems. How can I determine if it's a bug in Parallels? The app is here: http://www.chessimo.com/trainer/index.php?lang=en&page=11 . It requires .NET 4, but is otherwise a one-click affair. When launching it under W7-x64, it throws a runtime error '76': Path not Found and quits. Thanks for any advice Jeremy
