Exception occurred: System.DllNotFoundException: Unable to load DLL 'AnselSDK64'

I re-installed SE and it started OK.

Opps, it came right back after a few restarts. Tested with no antivirus as well. Same thing, take a while then same error.

Hello, Dan,

sorry to hear that you are experiencing this issue again.

Can you please provide more information? It would be good if you can provide new log file to see if the problem is still the same as you reported initially.

Also... what exactly you mean by "after few restarts"? Do I understand it correctly, that the game was working fine, you were able to play for some time and later, when running the game again as usual, you got this issue? You changed nothing in the meantime on you PC?

Any other additional information that you can think of sharing would help as well.

Kind Regards

Hello, the same error is happening to me as well. I was playing with some friends two days ago, everything was fine. Then I tried to open it yesterday and the game just crash after the splash screen. I opened the log to see what the problem was and I saw this line:

- Exception occurred: System.DllNotFoundException: Unable to load DLL 'AnselSDK64': A certificate was explicitly revoked by its issuer. (Exception from HRESULT: 0x800B010C)

I never touched my game files and I installed the game last week and all went well until yesterday. I attached the log for you to see

Hello, Dan and Yoann,

sorry to hear that you are still experiencing this issue.

Can you please try to go to your Steam\steamapps\common\SpaceEngineers\Content folder and rename or delete the Videos folder? This helped one player with not the same error in log, but similar symptoms.

Let me know if it worked.

You can also try to add "-skipintro" argument into Space Engineers launch options in Steam (right click on SE – Properties – General – Launch Options down in the bottom).

If nothing from above works for you, you can overcome this issue temporary by deleting the AnselSDK64 file in Steam\steamapps\common\SpaceEngineers\Bin64, verify game data through Steam and the game should work. If this works for you as well, as mentioned by other player, you don't need to reinstall whole game over and over.

While I know this won't be ideal resolution, it can help you save time until we manage to reproduce this issue on our side and report it internally.

Thanks in advance for writing me back.

Kind Regards

So far, deleting the dll and reverifying the game files worked, I'm gonna keep doing this if it happens again. If somehow it doesn't work anymore I'll let you know

But just to let you know, I have to delete the .dll and reverify each time I want to open the game. It's almost like it gets corrupted or something, would it be useful to send my dll the next time it crashes?

Hello, Engineers,

yes, I know. I did write that you would need to do this before every launch of the game, sadly.

You can also try to disable the Ansel on your PC ultimately. That should stop this functionality to run at all on your PC, thus the game should not try and load it.. and you should not experience the crashes.

However, this is far beyond the game itself, or something that we should give you steps how to do that. If you are willing to try, please search online how to do it at your own risk.

Kind Regards

Hello, Engineer!

Because there is no new comment from you, and we are unable to reproduce the issue on our own, I will close this thread now as outdated.

If you or any other player will experience this issue again, please make a new thread and provide all needed info there.

Thank you for understanding.

Kind Regards
