DOOM 3 (v1.3.1) [GOG]

So what are we supposed to do? My doom isn't steam or BFG etc. When I loaded it I gave it my cd key. Worked great.When I used this patch it asks for a cd key but it won't accept any key at all. Even the cd key box is weird. I'm trying to get a picture of it so every can see.So now I once again have to uninstall and reinstall and still won't be able to use the mods I want to.

DOOM 3 (v1.3.1) [GOG]

when(with winrar) i extract the patch in the main doom 3 folder ("C:\Program Files (x86)\Doom 3\") the system asks me if i want to overwrite the files.I press overwrite for all the files but in the log of winrar is written "impossible to create the file",access denied (it says it for every files or folder),then i'm unable to install this patch.

For help getting started, see the online documentation in the wiki. You need to provide your own game IWAD. If you do not have a copy of a doom-engine game, the easiest way to obtain them is to purchase them from Steam or GOG. When you download them from either of these stores, ZDoom will automatically find them.

ZDoom supports using FluidSynth for MIDI playback. To use it, extract libfluidsynth.dll to the same directory as zdoom.exe and then configure it from within ZDoom. FluidSynth is bundled with GZDoom since v3.1.0, so this separate download is only useful for older versions. 041b061a72
