If you are installing NWN1 to a newer PC, check the readme file for suggestions.
Required NWN1 files:
The file named "alfa_1_8.tlk" needs to go into your NWN1 install directory, in a folder named "tlk" which you may need to create for this purpose. All of the 18 files starting with "ahp_" are .rar files and need to be extracted into your "hak" folder.
Optional NWN1 files:
The 9 files starting with "ALFA_pack_" , "APP" , "app" and "portraits" all contain optional portraits. These can be extracted into your NWN1 install directory, to a folder named "portraits". You may need to create this folder for this purpose. The music haks have been uploaded to a separate folder. Simply extract these to your "music" folder in your install directory.
Since the 1.23 update, all Player side downloads are done via the NWN2 Auto-Downloader. Simply log into your server and NWN2 will automatically download all the haks and pwc files for you.
