2. Restart your PC
You should try rebooting the computer manually to ensure there is no temporary system glitch present. Sometimes potential glitches or cache data issues can affect the program launching or any kind of errors.
3. Run the Game as an Administrator
Make sure to run the game executable file as an administrator on the PC to allow the user account control access. To do that:
- Go to the installed UNCHARTED: Legacy of Thieves Collection game directory.
- Right-click on the application file on your PC.
- Click on Properties > Click on the Compatibility tab.
- Click on the Run this program as an administrator checkbox to enable it.
- Once done, click on Apply and then OK to save changes.
- Finally, just double-click on the game app file to launch it.
If in case, you’re running the game via the Steam or Epic Games Launcher then perform the same steps for the respective game client too.
4. Retry launching the game
It’s also recommended to retry launching the game multiple times so that it can get past the specific error and launch. A couple of affected UNCHARTED: Legacy of Thieves Collection players have found this trick useful.
5. Press the ALT+ Enter Keys multiple times
You can also try pressing the ALT + Enter keys multiple times once you’re in the UNCHARTED: Legacy of Thieves Collection game interface to easily switch between the windowed and full-screen windowed modes. It can also come in handy to several players.
6. Set Launch Options to Windowed Mode
Try launching the game in Windowed display mode to check if that helps you or not. Sometimes a computer with an average hardware specification can cause several issues with the fullscreen display mode while running the game.
- Open the Steam client and go to Library.
- Right-click on Uncharted Legacy of Thieves > Select Properties.
- In the General section, click on Set Launch Options.
- Next, copy & paste the following command-line argument:
-windowed -noborder

7. Rollback Graphics Drivers (v517.48)

8. Do a Clean Installation of the Graphics Driver
If there is no update available for your GPU then you can go to the official graphics card website from the links below and search for the model of your graphics manually. Make sure to download and install the latest GPU driver for your model number as per the manufacturer.

Here unnecessary external peripherals are like a printer, an additional keyboard/mouse, USB dongles, not-in-use wireless receivers, USB dock stations, RGB lights, and more.
12. Update Windows
If you’re running an outdated Windows version or build number for a while then make sure to follow the steps below to check for the same.

You should follow this in-depth guide to use the Windows Media Creation Tool to easily reinstall or update the current Windows build on the PC. If you want to perform a clean and full installation of Windows that means wiping out all the data from your C: drive or whichever drive you’re using for Windows installation. So, make sure to take a full backup of the all-important data like documents, media files, apps, etc.
14. Use Debug Mode in Nvidia Control Panel
As the name suggests, Debug Mode of the Nvidia Control Panel program might help you to detect the potential issue with the Uncharted Legacy of Thieves Unsupported CPU error while launching the game. This Debug Mode basically reverts the clock speed of the GPU and GPU RAM back to its default settings. To do so:
- Launch the Nvidia Control Panel program.
- Click on Help on top > Click on Debug Mode.
- Now, you can try launching the Uncharted Legacy of Thieves game to check if the problem is still bothering you or not.
15. Set a Virtual Memory
The chances are high that setting up the paging file size for the virtual memory should be equal to or higher than the RAM capacity of the system. Overall, you’ll have to increase the virtual memory size on your PC from the storage space so the respective game can run properly using the extra virtual memory space. If you want to change the virtual memory paging file size, then follow the steps below properly:
Please Note: You must be logged on as an administrator or a member of the Administrators group to complete this process. The network policy settings may also cause such issues if your computer is connected to a network.
- Click on the Start menu > Search and open Control Panel.
- Click on Performance and Maintenance > Go to System.
- From the Advanced tab, click on Settings under Performance.
- On the Advanced tab, click on Change under Virtual memory.
- Under Drive [Volume Label], click on the drive that contains the paging file you want to change.
- Under Paging file size for the selected drive, click on System Managed Size > Click on Set.
- If this option hasn’t been flagged, restart the PC after flagging it.
- If the system paging file size is used to be System Managed then under Paging file size for selected drive, click on Custom size.
- Now, type a new paging file size in megabytes in the Initial size (MB) or Maximum size (MB) box. [It should be 1.5x-2x higher than the physical RAM]
- Finally, click on Set > Restart the PC to apply changes.
16. Use the Dedicated Graphics Card
It’s highly suggested to always use the dedicated (external) graphics card on your desktop for heavy games and applications so that you can get higher graphics performance all the time. To do that:
For Nvidia GPU:
- Right-click on the blank desktop screen > Open Nvidia Control Panel.
- Go to 3D Settings > Click on Manage 3D Settings.
- Open Program Settings > Select Uncharted Legacy of Thieves from the list.
- Select preferred graphics processor for this program from the list.

- Once done, select High Performance from Graphics Settings.
- Finally, reboot the PC to apply changes.
17. Install Microsoft Visual C++ Redistributables
If your Windows system doesn’t have Microsoft Visual C++ Redistributables installed or even already installed, make sure to reinstall it manually by following the steps below.
- Open the Start Menu > Type apps & features and open it.
- Click on the Microsoft Visual C++ program(s) from the list one by one.
- Click on Uninstall and follow the on-screen instructions.
- Once all Visual C++ programs are uninstalled, reboot the PC.
