I'm have two problems. The first is that the Neverwinter Nights installer doesn't create nwnmain and nwnserver (I tried it as both user and as root). As user nwn was created, but NWN couldn't find the HoTU expansion.
I used the installers in this order:
nwn_1.29-multilanguage-2.run
nwn.sou_1.3x-multilanguage-2.run
nwn.hotu_1.62-multilanguage-2.run
nwn.hotu_1.68-german.update.run
EDIT:
Does the
for each one? Not only after the last expansion?Important!!!
You have to update neverwinter nights to the latest version!
