i just bought neverwinter nights 2 and it has a 3 part download. just wondering before i start how i go about this? is it download all 3 then install? or can i do it one at a time? will it matter?

It's a split installer, which means you must have all three parts. Once it's all downloaded you should have:

setup_nwn2_complete_2.2.0.10.exe
setup_nwn2_complete_2.2.0.10-1.bin
setup_nwn2_complete_2.2.0.10-2.bin

Make sure they are all in the same folder with admin permissions, and that your install drive has plenty of temp space, then run the .exe file.

thanks a bunch.

I don't know if it is a big deal or if I'm that bad with computers but would it make any sense for gog to put that kinda information in with the game description. if there are other games with similar setups. thanks again

See, that would strongly imply the need to download the three parts. Though maybe that's just me.

It's pretty self-explanatory, and hard to mis-interpret:
(Part 1 of 3)
(Part 2 of 3)
(Part 3 of 3)

It doesn't come any simpler than that.
