I'm sorry, should have provided more details initially.

The game crashes on launch. I click the launch button through the Epic Games Launcher (EGS), or I run the game executable (".exe") directly, but it crashes regardless of the launch method. I've tried running the game as both my current user account and with administrator privileges, but the crash persists.

Same issue for me. Just cleanly installed from Epic store, and the game just will not launch. If I launch from the Epic launcher, it does nothing. If I launch sins2.exe directly from the folder, I get "sins2.exe - Application Error: The application was unable to start correctly (0xc0000142). Click OK to close the application."

I've tried the whole array of compatibility options including Windows 8, Run as Admin, DPI changes and more, same issue.

Specs:

Windows 11 Pro 23H2
Gigabyte AORUS Elite X570 Motherboard
Ryzen 7 5800X
32GB RAM
GeForce RTX 3070Ti

All drivers up to date as of last night.

Interestingly, I also have a Gigabyte AORUS Elite X570 motherboard. Weird coincidence?

Nope, literally clean installed the game from Epic and it does this. Tried Verify too, no change.

Annoyingly, I did have about 7 hours in this game not long after it launched and it ran fine then (same PC). But stopped playing as I felt it was a bit of a step down from Sins 1 and I didn't enjoy it as much. Left it a while, formatting and reinstalling my PC in the interim. Decided to give it another go as I'm sure it's had updates since, and now it won't even start. The game conspires against me getting a worthy sequel to Sins 1   

wow, forum spam.

Not seeing an update here so assuming no fix, but wanted to report that I have the same issue. Standard install no Mods and not OC'ing system. The Sins II Testing Edition plays but no joy on the standard install.

System Info Below:

G.SKILL DDR5-6000 (64GB | 32GB Channel 1 & 3)

that's really weird. This is not going to solve anything but just wondered if you watched task manager if it even showed up.

Can confirm, test version working, regular version does not. There is no active process, because game doesn't start, if launched from binary (sins2.exe), not from Epic Launcher, with administrator privileges you getting error.

Still broken for me too. Just reinstalled it to check.

I've pretty much given up on this game now.

Excellent. I'll do that 👍🏼

I stopped being able to run it in February. It updated today, and actually works again after a 6 month break. I guess while they were writing all that DLC they thought they would fix the main game at the same time.

I've got hundreds of games over in my Steam account and never had a problem like this with any of them.

Same for me. It works now after the big 4.5gb update.
