If you run a Steam Verify operation against this game, does it find anything to fix?


If not Please try a **clean** reinstall:

- Remove the game from Steam (uninstall)
- Manually delete all these files and folders, if still there:

...\Steam\steamapps\common\Cities_Skylines\
...\Steam\SteamApps\workshop\content\255710\
...\AppData\Local\Colossal Order\Cities_Skylines
(first move the /saves/ folder elsewhere to keep your save games)
(To see the AppData folder you'll need to enable View Hidden Items in File Explorer)

- Install the game again and see if it runs now.

Good luck with that!

Steam verify said everything was good, I uninstalled and deleted all files related to the game, did a fresh install and still get the same error message.

I see, you may have a Windows problem then. Any idea what changed in that regard between the last time this game worked and the first time this problem happened?

What if you make a new Windows user on this machine, and log into it as that? Does the game work there?


I found this hit on that error:
I don't fully follow the issue described there but it involves MikTex and the Windows PATH statement. Anything new installed in that area?
