I've tried both the 64 and 32 bit builds from moddb but both just flash black screens and shut off bringing me back to desk top (i'm aware my computer is no gaming pc but this shouldn't happen for this) vershion 1.21 of base game still works however.

Hi, sorry that it doesn't work for you.

What version did you try?

Could you open a bug report at bugs.arx-libertatis.org and include the contents of your arx.log file so that we can get this fixed.

arx.log is in My Documents\My Games\Arx Libertatis for Windows XP and in Saved Games\Arx Libertatis for Vista and newer.

I bought the steam vershion (sorry gog) and now that you mention it do you think it has to do with the steam client refusing to operate arx fatalis and th liberatatis at the same time?

No, Arx Libertatis does not interact with the Steam client at all.

Would this help
[Download Arx Libertatis from here. Extract the zip file.

Install the required dependencies by running the command below:

sudo apt-get install cmake g++ libdevil-dev zlib1g-dev libfreetype6-dev libglew1.5-dev libopenal-dev libboost-program-options1.46-dev freeglut3-dev libopenal1 mesa-common-dev libgl1-mesa-dev libboost-all-dev libguichan-dev

Run the commands below from the newly extracted Arx Libertatis folder:

mkdir build && cd build && cmake ..
make

Arx Libertatis is now installed. In the build directory, you will be able to find arx executable.

We still don't have game files yet. A full version of Arx Fatalis can be purchased from GOG or Steam. For this guide we will use free game demo downloaded form FilePlanet.

Extract the demo files. Now we need to tell the arx executable about game data. Go to the demo folder and run the commands below.

cd demo (or whatever name your folder have)
cabextract Setup1.cab
cabextract Setup2.cab
cabextract Setup3.cab

Now create a new folder and name it Data or Game Data or something else. We will copy necessary files from the demo folder to the data folder. The game executable will look for relevant files in this folder.

If Data is your destination directory, create a data/misc directory and copy the following files:

demo/bin/Arx.ttf to data/misc/arx.ttf
demo/bin/data2.pak to data/data2.pak
demo/bin/LOC.pak to data/loc.pak
demo/bin/Logo.bmp to data/misc/logo.bmp
demo/data.pak to data/data.pak
demo/SFX.pak to data/sfx.pak
demo/SPEECH.pak to data/speech.pak

Change all file names from uppercase to lowercase. Almost done.

Now tell the arx executable location of data folder by using -d option. I used the command below to run game. Make a script or custom launcher if you want for quickly launching the game.

'/home/nitesh/Desktop/arx-ArxLibertatis-dbb8ca7/build/arx' -d '/home/nitesh/Desktop/data'

Great work has been done by Arx Liberatis team. The game runs super duper smooth on my ATI HD 4650 card at max settings and 1920 x 1080 resolution.

Same problem here. Black screen flashes up and nothing happens.

I have tried the above solution no success.

There is a path error saying "Cannot locate nsc3.tmp/dxsetup"

Also the config file has anti-aliasing true by default n an integrated graphic card Intel which is what my Win XP is supported. I think the Arx Libertatis cannot initiate on integrated chips or they have some dependencies in terms of driver that conflicts with the Direct X namely vertex shader, etc.

But, I can play GOG original but arx libertatis doesn't start the game with just a flash and exits

I request some guidance to work this issue and anyway to detect which driver (OpenGL or D3D) is used by Arx Libertatis? I want to try by changing the entry to D39 Direct 3D

AHHHH what does any of that mean????? I hate dealing with mods D:

I'm also having the exact same issue. :(
