Solved Program not opening at all.

[WarmMuffinPants]

Hey there,
The program itself is crashing before anything loads, I am not getting to the world select, it does not even seem to be starting.
I am running a Windows 10 22H2 system with an AMD Ryzen 7 5800X, 32 GB of RAM, and an NVIDIA GeForce RTX 3070, I added the event log from start up. I am not sure where to go from here.

Your could try installing .Net 9 again, that worked for me:

For those that are getting nothing open up when starting KSA, once I installed the latest .Net 9.0 runtime, it started up fine.

Download .NET 9.0 Desktop Runtime (v9.0.11) - Windows x64 Installer

dotnet.microsoft.com

If the link doesn't work, search for .Net 9.0 runtime (you'll likely need the desktop version). Usually no restart is required.

I also would like to say to the developers, I was blown away by the quality of the game. You are already way ahead of all other space sims I've played. Keep up the great work!!!

That was a good idea that I had not thought of, but unfortunately it didn't work. Thanks anyways!

Same issue here, the app doesn't start, I installed .Net. Nothing in task manager, any process

Okay great, there's people on Win10 22H2 with this issue. My game does not load at all, and I'm on Win10 20H2 + RTX 3080ti w/ NV 551 driver

Could you all please post the exact versions of your GPU driver installed?

PS: Can you bring this up to others in the Discord / complain more? I can't (Lol) for reasons and I really want the Devs to try to expand the OS + old driver compatibility by as much as possible

Can you go into "Event Viewer" on your Start Menu, then go to Windows Logs -> Application Logs after launching KSA?

You should see a red "Error" that KSA makes, can you post the page?

I would try to reinstall that program (delete the icon as well and all files) and try to load the game on full solar system on 1k graphics, it then should work

I have reinstalled the game a few times, it does not open at all, so I can not get to the screen that allows me to choose full solar system.

I had the same problem and discovered that my graphics driver had no support for the Vulkan renderer. I updated my graphics software and was able to start the game. Well, had to downgrade the settings, maybe it's time for a new gaming notebook when KSA reaches a decent beta stage.

The error call stack in the Windows Event View looked like this:
Application: KSA.exe
CoreCLR Version: 9.0.1125.51716
.NET Version: 9.0.11
Description: The process was terminated due to an unhandled exception.

OK, I got it working, I needed to turn off "Exploit Protection" in the "App and Browser Control" settings. I am not sure which setting it is, so I disabled all of them for this app as I don't have time today to figure it out. I am attaching an image walk-through.

This last solution did not work for me, and since this is marked as "solved" I might make my own thread.
