Cities: Skylines (Steam) - Game can't be launched

[Tom085]

Describe your issue
Game can't be launched

What is your game version?


What expansions do you have installed?
After Dark, Snowfall, Natural Disasters, Mass Transit, Green Cities, Parklife, Industries, Campus, Sunset Harbor

What mods are you using?
I've disactivated all one

Please explain your issue is in as much detail as possible.
I've bought the game on Steam. Since 2 weeks, game can't be launched. When I select "Play" ("Jouer" in French), game says : "Game cant' be lauched" : "Le lancement a échoué" in French).
I try to re-install the game, re-install Steam, but all my games are working except Cities Skyline...

Can you replicate the issue? If yes, please explain how you did it.

Post your output and error Log or on Mac it is called player log.

Hi,
Thank you for answering.

My output_log below :

From that log the game does not think Steam is running, which it must be for the game to start. Did you try running from cities.exe directly perhaps?

Delete that log file then run the game from the Steam PLAY button only. If it still fails please attach a new output log here, thanks.

 

[Tom085]

I deleted former output_log file. I've run the game from Steam. Launch has failed (see screenshot of my first message) but no output_log file has been created...
Could you help me ?

 

[AndrewT]

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!

 

[Tom085]

I've done that you required but, problem is still there and no outpu_log file created. Maybe the launch failed before to try a log ?

 

[AndrewT]

Clearly, yes, but I'm not sure what could do that. This game does not have any dependencies in Windows.


If you run cities.exe directly what happens? Any Windows error pop up?

Any idea what change or update in your computer triggered this problem?

 

[Tom085]

Same problem when I use cities.exe
I don't know where the problem could be from.
2 weeks ago I re-install the game because I thought it was slower than before. And since that, I can't launch the game. So I've tried to re-install Steam, that doesn't change anything. So I request your help.

 

[AndrewT]

Still no output log?

What. if you make another user in this Windows installation, log into it, and install and run the game there?

 

[Tom085]

How ! It's working from the other user session... I really do not understand how it could happen !

 

[AndrewT]

I can only assume the Windows user profile for the first user is corrupted or has some other problem. If you have some source of Windows support they may be able to help you fix that, or perhaps a clean wipe and reinstall of Windows might be necessary.

Good luck with that!
