This is why in this guide, we’ll provide you with every single step that you can undertake on your PC and resolve your problem. We guarantee that by the end of this guide, you’ll no longer face crashing or launching issues with Supermarket Simulator and finally run the game smoothly on your PC.


Here’s a quick look at what the solutions involve:



If your Supermarket Simulator is crashing or not launching through Steam, remove your saved files to test without them. If the issues continue, update your driver and operating system, and cleanly reinstall the game from Steam.


That’s only the tip of the iceberg, so let’s get into an in-depth explanation!

How to Fix Supermarket Simulator Crashing or Not Launching?

Note: Before you start, are you sure that the Supermarket Simulator game is up to date?

1. Backup & Remove the Saved Files

The first and one of the most important steps when Supermarket Simulator crashing on startup or not launching is to remove your saved files. This means removing the files from the game’s directory, to make sure that the software is not crashing due to something in your game world.


Such problems appear because of in-game bugs that affect the outcome of launching the game, which ultimately produces crashing. Hence, removing your saved file from the %AppData% folder should exclude most possibilities for crashing on startup.


This is the folder containing the saved files on Supermarket Simulator:


  • C:\Users\[PC Name]\AppData\LocalLow\Nokta Games\Supermarket Simulator\

If you don’t know how to access the files, follow the steps below:


  • Click the Start Menu from the Windows Taskbar.
  • In the search, type exactly as follows %AppData%.

  • In there, you’ll find a folder named “Nokta Games.”
  • This is the destination of all your saved game files.
  • Backup and remove ALL the files from this folder.

The files are called “”, where “n” is the number of the saved file. We recommend copying ALL saved files into a folder on your Desktop as a temporary backup and deleting all the files from the “Nokta Games” folder.


Without the saved files, launch the game from the Steam launcher and check whether the crashing or launching issue persists. For more information on locating the game’s directory, check this guide.

Reminder: If you still face the issue, put all your saved files back into the “Nokta Games” folder.

2. Update the (GPU) Graphics Driver

Another reason why your Supermarket Simulator is crashing or not launching on your PC is due to outdated video graphics drivers. This one is quick and easy to solve and you only need to download the newest executable file from the official provider for your graphics card (GPU).

  • If you’re using an AMD video card, get the latest AMD Drivers

4. Optimize the Memory of your PC

If your Supermarket Simulator is crashing or not launching through Steam, your computer might have memory insufficiency. This is common, especially when you have a lot of ongoing tasks and processes that you don’t really need while playing.


You can quickly relieve the memory of your computer by ending tasks from the Task Manager, which consumes a lot of resources you don’t really use.

Here’s how to manually end tasks and processes from the Task Manager:

  • Right-click anywhere on the Windows Taskbar.
  • Click on the “Task Manager” tab that appears.
  • Next, click on the “Memory” tab to sort all tasks.

Tip: One of the largest RAM consumers is the Google Chrome browser and all tabs opened within!

5. Verify the Integrity of Game Files
