Zero6823: So, I just purchased this game off gog and downloaded it today and I found I didn't have any need for patches. I guess gog took these patches and added the files to their installation download package?

My computer is win 7 and has amd graphics card.

Boilpoint: That would be odd (but maybe not unheard of). I haven't noticed any updates to the installer for quite a while (if ever?).

Gunblade0: guys i have a HD7770 1GB and when i try using 3D acceleration with or without any of the fixes, the game sends me back to the main menu with a message saying "your graphics card may not have enough memory to support these settings"
seriously game engine?

Marlor: Step 1 is: "get rid of GOG/Steam Versions" + Links to Piracy

Why is this postet here and even stickied?

medievil1: huh?? what links to piracy?? if they have the gog/steam version they bought the game, if you mean the original ExE.. so what??

jnisbet: I've gotten the GOG version of Jedi Knight working in 64-bit Windows 10 with 3D acceleration AND music by doing three things:

1. Copied the DDraw fix (the ddraw.dll wrapper) to the game folder. See the URL in the 1st post.

2. Copied the pre-patched JK Unofficial Patch to the game folder. See the URL in the 1st post.

Doing those two things got me 3D acceleration (after I switched to a 32bpp resolution in Setup), but no "CD" music (i.e. no music after walking out of the bar). This made sense at first, since I was now using a non-GOG version of JK.exe, but it turned out that it wasn't that and that the fix to get music working with the unofficially patched executable was very simple...

3. Renamed JK.exe to something else (I chose JediKnight.exe) and updated the shortcut.

When I saw that that fixed the problem and I was getting music again, I went digging in the registry and found the culprit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Custom\JK.exe, under which there were a lot of compatibility settings. That's not the usual place where compatibility settings are stored when you run apps and it was the ONLY entry there, so my suspicion is that the GOG installer specifically created it. Anyways, once I deleted that key, I was able to rename the executable back to JK.exe and still got music. For people who aren't comfortable with editing the registry and want a simple solution, though, renaming JK.exe to something else does the job just as well. Try it if you've gotten 3D acceleration working, but are now not hearing music after you leave the bar.

Marlor: Not The exe, the komplete Game:

jnisbet: I've gotten the GOG version of Jedi Knight working in 64-bit Windows 10 with 3D acceleration, mod support AND music by doing three things:

1. Extracted this pre-patched JK Unofficial Patch to the game folder. This enables mod support and is needed for the next step.

2. Extracted this 32-bit Display Mode Patch to the game folder. This is one of the ddraw.dll files that fixes 3D acceleration.

After doing those two things, I was able to go into Setup->Display and select a 32bpp resolution (which you need to get working 3D acceleration instead of a black screen). If you still can't select a 32bpp resolution, then try extracting [url=http://jkdf2.com/files/ddraw_(hack_viewport3_clear2).zip]this alternate ddraw.dll[/url] to the game folder, instead.

At this point, I had working 3D acceleration and mod support, but no "CD" music (i.e. no music after walking out of the bar). That made sense at first, since I was now using a different version of JK.exe than the GOG version, but it turned out that it wasn't that and that the fix to get music working again was very simple...

3. Renamed JK.exe to something else (I chose JediKnight.exe) and updated the shortcut.

When I discovered that that fixed the problem and I was getting music again, I went digging through the registry and found the culprits:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Custom\JK.exe
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Once I deleted the JK.exe key and the reference to JK.exe under the Layers key (don't delete the Layers key, just the value inside it which references JK.exe), I was able to rename the executable back to JK.exe and still got music. For people who aren't comfortable with editing the registry and want a simple solution, though, renaming JK.exe to something else does the job just as well. Try it if you've gotten 3D acceleration working, but are now not hearing music after you leave the bar.

farth: Not work, I have small picture of game in the left-top screen.

Astaldo711: I was wondering this myself. Not so much about piracy but why come to the GOG website to point to a website where the first step is to uninstall the GOG version?

jnisbet: That sounds like a DLL issue. Are you using the ddraw.dll that's included in the zip from Step 2 of my post? If so, then try the first two ddraw.dll versions from the following page (the third and final one is the one that I linked to, since I had success with that one):

http://jkdf2.com/23-step-6-3d-acceleration-fixes-directx-wrappers-optional-depends-on-your-graphics-card-and-operating-system

If both of those don't work for you, either, and you happen to have an AMD/ATI graphics card, then download and install the AMD/ATI fix from that same page. Try combining that with each of the three ddraw.dlls. One of the combinations will hopefully work for you.
