I had to install a clean Windows 7 VM. Before I did that, though, I had copied all the files from my old mac to my new one, including the Applications (Parallels) folder containing all my Windows 7 applications. I had hoped they would automatically be used when the new clean VM was set up and started, but they're not. I attempted to transfer some of the Windows applications to my new Windows Program Files folder, but found they're all .app files instead of .exe. What should I do?
