Sure Nesrie, "Since you're using Windows 7 you need to know, that the UAC (User Account Control) scan might cause the GOG.com installer to launch
with slight delay (up to a few minutes). Larger files will "generate" longer delay. Taken from GOG account download page
Has very little to do with what you said, since that's only when you run the installer. It happens in Vista also, as they both scan EXE files for compatibility issues before launching them.
D2D has issues with that as well.
