Installed Windows Vista and Windows 7, planning on installing Windows XP. I open either copy of windows, then download an exe file to the desktop. If I double click the exe file, Parallels opens the other version of Windows. For example if I have Vista open, double click an exe I just downloaded, Parallels launches Windows 7. How can I Tell parallels to only open Windows files in the Current windows installation? So if I have Vista open and launch an exe, I want that exe to execute in the currently open version of Vista. Any help you could provide would be greatly appreciated. Thank you.
