Hi Flashwit - are you on 64bit?
if so - there is a slight difference with the registry path.
Look for the Wow6432Node folder within the Local Machine --> Software
Then create the Bioware --> NWN --> Neverwinter within that node, and then add the Path / Location keys.
The only other possible issue would be firewalls - you definitely granted access to the program in the firewall?
I will try to make some modifications to the program, so it will check the local directory first, before looking in registry.
Registry reading was meant to make it easier to use, eg: will work no matter where you put the program on your computer, but like me, and like the server, you don't have a conventional install, NWN does work, if you drag and drop the folder all over the place, so the registry entry is not a necessity.
In the mean time, try those registry entries, and see if that solves it.
@ Mary: Why does he end up getting multiple icons?
He would only get multiple icons, if he opens the downloader multiple times.
If he opens it, leaves it running, and does not exit it with the x icon, it should remain open, and available to use.
Maybe we can organize a skype share session so he can show me what he means?
