For CC that has problem, wut are they? Do them use there own install app? Am thinking ppl wut have small partitions like u mayb like to know wich ones.
NWN say x86 folder not gud but never say why. It be gud to know to figger stuff like this out.
I think it past lot of builders used nwconthak.exe in nwn/utils which makes a very simple hak installer for windows. That could not work with GOG default path but its pure speculation from me.
BUT. Thats a case of very old custom content, nobody is using that past X years. AND. That exe installer should be possible to extract without installing, I think.
