I was told by a friend that I could take my copy of never winter nights and install a no cd required program. However all those I've used have not worked. Is it true? can I do It? Is this a "crack"? Could someone explaine how to do this or direct me to a forum that will show me how to do it?

No-CD Instructions:

Install the game - Full Installation.
Apply the official Neverwinter Nights v1.20 Update - Use the buildin game updater!
Replace the original NWMAIN.EXE executable with the one from the Executable Archive.
Play the Game!

I have not tried it though.

i use a no-cd with my Neverwinter Nights.

be sure to make a backup of the original .exe file that you are replacing, though... so you can revert back for future updates.
