How to fix the Error 7812021 in Tower of Fantasy

There is an alternate technique that users in the community have reported working for them if correcting the mistake through the client via a repair does not make things better. Although if you're not accustomed to searching through computer files, this approach could seem a little unconventional. the following steps:

• Open up your computer settings. Go to Apps.

• You should see a tiny button labeled "Optional features" while in Apps and Features. Toggle that.

• The "Add a feature" button up top should be clicked. Install Graphics Tools by performing a search.

• After installing Graphics Tools, close that window by pressing the Windows key and R. By doing this, the Run command window will appear. Enter "dxcpl" into that window. Hit OK.

• It will now display the DirectX Properties Window. You should select "Edit List." To access the QRSL.exe and TOF launcher.exe files, click here and then on "Download." When you install Tower of Fantasy, you should have both of them. You can use the screenshot we've provided below to see exactly where to look for them. Click "Ok" once you've located both of these files.

• Make sure to select "Force On" under Direct3D/DXGI Debug Layer in the DirectX Properties Window once more. Next, alter the feature level limit under Device Settings from None to 11. Additionally, you should select Disable Feature Level Upgrade. Use each of these modifications.

• Restarting your computer is all that is necessary once you're finished. After that, reload Tower of Fantasy.
