Assassin's Creed 1 Crashing fixed for good

[cuts.]

I tried setting the launcher on compatibility mode but what really worked for me was going to the game's folder and switching the 2 launchers names.
The one that ends with dx9 change it to dx10 and the dx10 change it to dx9.
Works perfectly for me. And it works because steam automatically uses the dx9 launcher and that's what makes it crash, if you change their names steam will still launch the one named dx9 but this time it will actually be the dx10 and will not crash!
Hope this helps :)

Game pauses after 3 seconds and crashes on the 5th second, going back to desktop.

OK so I am not going to do it again on my machine, but it goes something like this:-
1. under games pull down menu (top left between friends and help) select “add non-steam game to my library”.
2. Select browse at bottom of newly opened menu and navigate to “C:\Program Files (x86)\Steam\steamapps\common\Assassins Creed” or your equivalent depending on where your steam games are saved.
3. Select “AssassinsCreed_Dx9.exe” and press open.
4. Etc. etc. etc.

I did the renaming of files technique, and then PJ Maybe's idea. Nothing worked for me. Still crashes 5 seconds in.

Found my solution somewhere else after posting for help. The solution that helped me was to disconnect the machine from the internet, suggesting the crashing was being caused by DRM/Telemetry service the game uses. Another set firewall to block all traffic and it for them.

What IPs or domain names need to be blocked?

He just said "I just set my fire wall to block all traffic and the game launched." Never said any specifics and I am not tech savy enough to even mess with that stuff. No idea and not making suggestions since I don't know.

Encontre la solucion para windows 7, ve a donde se encuentran los archivos del juego, busca el "AssassinsCreed_Game.exe" y da click izquierdo, propiedades, despues seleciona pestaña compatibilidad, y seleccionas compatibilidad con window 7 y hasta a bajo ejecutar como administrador y aceptar, con eso funciona

I found the solution for windows 7, go to where the game files are located, look for the "AssassinsCreed_Game.exe" and left click, properties, then select compatibility tab, and select compatibility with window 7 and even under run as administrator and accept, that works

So... Hello from the 2020. Installed the game but it crashes on the startup (first video). What I've tried already (X means that the solution did not help):
1. X - Moved all videos into another folder (I thought maybe usual bug with the video. Sometimes it helps).
2. X - Renamed the AssassinsCreed_Dx9.exe and AssassinsCreed_Dx10.exe
3. X - Compatibility mode with: win 7, win vista.
4. X - Tried to run: AssassinsCreed_Dx9.exe, AssassinsCreed_Dx10.exe, AssassinsCreed_Game.exe, testapp.exe
5. X - Duplciated the AssassinsCreed_Dx9.exe and named it with Dx10. (To force steam use the Dx9 if it ignore the naming change).
6. X - Vice Versa. Duplciated the AssassinsCreed_Dx10.exe and named it with Dx9.
7. X - Added the Dx9 and Dx10 executable (as a non-steam game) into the steam browser.
8. FIXED: I turn on the offline mode in the Steam AND turn on the airplane mode on the laptop. (It seemed to be true that the game fails to connect with something and crashes on the try. There are some solutions to prohibit the internet connection for the game adding rule to the firewall. I think that it will help.)

There's no need to rename things, simply double clicked on the Dx9.exe and the game launches and runs just fine.

To find these files just right click on Assassin's Creed in your Steam Library. Select 'Manage'. At the pop-up box just click on 'Browse Local files' tab and then select the button that say 'Browse Local files' and a file on your computer will open up and you will see the two files in question. Just double click the Dx9 .exe one and the game launches.

Game fails on accesing "presence-heartbeat.xboxlive.com". Turn off network helps to open game without any problem on Windows 10 Pro 20H2
