The black box you are seeing is the launcher program hanging on the intro movies. This occurs either because of a video driver issue or issues with Windows 7 not having the full dlls from DirectX 9.0c (I haven't been able to determine which). Installing DirectX 9.0c also improves game performance.
This is the installation procedure I used on all the PCs in my house - both desktop and laptop. I run Win 7 and Win 8.1. I have used this method on all 7 computers without fail.
1. Download and install the DirectX 9.0c - http://www.microsoft...ls.aspx?id=8109. This will ensure you have all the necessary DirectX components to run the game and toolset. RESTART THE SYSTEM when install is finished.
2. Install game using a custom install. When you are given the path to the install folder, change the path using the browse folder button so that it is NOT installed in 'programs (x86)', but directly on C drive. Do not make any shortcuts during the install process. The directory should read c:\NeverwinterNights\NWN
3. Download the HotU 1.69 critical rebuild and install it (links below). I don't care what GOG or others say, the GOG "1.69 patched version" has multiple issues which are resolved by running the critical rebuild. It takes about 3 minutes to process and won't hurt anything.
4. Open your NWN folder and find nwmain.exe and nwn.exe.
5. Right click on these and select properties. Set them to run with full permissions, as administrator, and under compatibility mode windows XP service pack 2 or 3 FOR ALL USERS. I use SP3 for my system.
6. Update your drivers for video and sound. (go to the manufacturers of your cards' support pages. Laptop support pages can be very behind the times).
7. Disable intro movies as above.
8. If you still get the launcher issue then bypass the launcher by directly opening nwmain.exe. The toolset can be opened by directly opening nwtoolset.exe. I created shortcuts to these and placed them on my desktop. YOU DO NOT NEED COMPATIBILITY MODE FOR THE TOOLSET.
