4. Update graphics card driver

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:

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.

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.

  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 Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.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.
The Pro version of Driver Easy comes with full technical support. If you need assistance, please contact Driver Easy’s support team at support@drivereasy.com.

Try to launch Lethal Company 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.


5. Reinstall the game

According to some community users, if Lethal company doens’t launch for you, it’s probably becuase of some outdated mods, or mods conflicting with each other. To fix this problem, you can choose to reinstall Lethal Comapany and the installed mods altogether.

To uninstall Lethal Company from Steam:

  1. Launch Steam.
  2. Go to Library > Games, right-click Lethal Company and select Manage > Uninstall > Uninstall to remove it from your computer.
  3. Then go to the Steam folder on your computer, try to locate the files for Lethal Company there (which is usually found via this path: Steam/steamapps/common/Lethal Company), then remove all files there.
  4. Reinstall Lethal Company on Steam again.

Then try to launch Lethal Company and see if it launches well this time. If the problem remains, please move on.


6. Increase virtual memory

When Lethal Company doesn’t launch, it’s probably due to limited RAM space on your computer. To see if this is your case, you can try to increase the virtual memory to allow more RAM resource for the game to run. To do so:

  1. In the Search box, type advanced system settings. Then click View advanced system settings from the list of results.

    increase the page file size
  2. Under the Advanced tab, click Settings.

    how to increase the page file size
  5. Select your C drive and then tick Custom size.

  6. Type in the values for Initial size and Maximum size. Then click OK to save the changes.
  7. (Tips: Microsoft recommends that the virtual memory you set is no less than 1.5 times and no more than 3 times the size of your RAM. To check RAM on Windows, follow the instructions below. )
  • On your keyboard, press Windows + R keys simultaneously to invoke the Run box.
  • Type msinfo32.exe and press Enter.

    check RAM
  • Scroll down and look for the Installed Physical Memory (RAM) entry.

    how to check RAM

1 GB (Gigabyte) = 1000 MB (Megabyte)

So in my case, the recommended initial size is: 8 GB * 1000 * 1.5 = 12000 MB
For the recommended maximum size, it will be: 8 GB * 1000 * 3 = 24000 MB

After increasing the page file size, try to launch Lethal Company to see if it works now. If the problem still remains, you may need more specific troubleshooting by checking the system crash logs. To know how to do it, please move on to the next method.


7. Check the system crash logs

If your Lethal Company still refuses to launch at this stage, and you’re still inclined to do the further troubleshooting by yourself, you can try to analyze the crash logs created by your computer when the crashes happened.

If you’re interested in knowing more about analyzing your crash logs files, please refer to method 2 in this post we have: How to Check Crash Logs on Windows: View Crash Logs with Event Viewer

You should then find some error codes and/or error messages in your Event Viewer that might help. The codes or messages you see on your computer might be unique in your case, so we don’t have more general fixes here to suggest. But if you do find such codes or error messages, you can always search them on our knowledge base here: https://www.drivereasy.com/knowledge/ for further troubleshooting tips.


8. Repair system files

If you are facing persistent issues and none of the previous solutions have proven effective, it’s possible that your corrupted system files are to blame. To rectify this, repairing the system files becomes crucial. The System File Checker (SFC) tool can assist you in this process. By executing the “sfc /scannow” command, you can initiate a scan that identifies problems and repairs missing or corrupted system files. However, it is important to note that the SFC tool primarily focuses on scanning major files and may overlook minor issues.
