2. Repair and change Launcher file settings

The reason why Cities: Skylines 2 refuses to launch is probably that you have corrupt or damaged Launcher File settings. You can repair and change such settings to see if it helps.

To do so:

1. If you did a default installation of Cities: Skylines 2, the file will be at Local Disk >> Program Files >> steamapps >> common >> Cities Skylines II >> Launcher.
2. Double-click the launcher-installer-windows_2023.11.msi file to run it, then select the option to repair.
3. If this doesn’t fix the launcher issues, open the launcher-settings.json file with Notepad. Then change the variable from 0 to 1.1.
4. Save the file before exiting.

When the changes are made, launch Cities: Skylines 2 again to see if the problem is fixed. If not, please move on.

3. Add Cities: Skylines 2 to your antivirus exception list

The Cities: Skylines 2 not launching problem may also be caused by your third-party antivirus application. Since the third-party antivirus application hooks very deep into your system, it may interfere with Steam.

Since Steam consumes a lot of memory and CPU usage when running, many third-party antivirus applications may regard it as a potential threat and Steam may not run as expected. You can try adding Steam as an exception to your third-party antivirus application.

4. Update Windows

If your system isn’t updated regularly, there could be compatibility issues that can cause Cities: Skylines 2 not to launch successfully. To make sure that you have the latest available updates installed:

1. On your keyboard, hit the Windows key, then type check for updates, then click Check for updates.
   
2. Click Check for updates, and Windows will scan for any available updates.
   
3. If there are available updates, Windows will automatically download them for you. Restart your computer for the update to take effect if needed.
4. If there are no available updates, you’ll see You’re up to date like this.

Then try your Cities: Skylines 2 again to see if it launches. If the problem remains, please move on to the next fix.

5. Update graphics card driver

An outdated or incorrect display card driver could also be the culprit to your Cities: Skylines 2 not launching problem, so if the above methods don’t help Cities: Skylines 2 to launch, it’s likely that you have a corrupted or outdated graphics driver. So you should update your drivers to see if it helps.

There are mainly 2 ways you can update your graphics driver: manually or automatically.

Option 1: Update your graphics driver manually

If you’re a tech-savvy gamer, you can spend some time updating your GPU driver manually.

To do so, first visit the website of your GPU manufacturer:

• NVIDIA
• AMD
• Intel

Then search for your GPU model. Note that you should only download the latest driver installer that’s compatible with your operating system. Once downloaded, open the installer and follow the on-screen instructions to update.

Option 2: Update your graphics driver automatically (Recommended)

If you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):

1. Download and install Driver Easy.
2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
   
3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system. (This requires the Pro version – you’ll be prompted to upgrade when you click Update All.)
   Note: You can do it for free if you like, but it’s partly manual.
4. Restart your PC for the changes to take effect.

Launch Cities: Skylines 2 again and see if the latest graphics driver helps it to launch. If this fix doesn’t work for you, try the next fix, below.
