GUIDE TO FIX WINGETUI NOT LAUNCHING

[marticliment]

WingetUI 3.0.2 has been released, fixing most of the crashes. You may download it from here

WingetUI 3.0.2 should not crash anymore. Apologies for the inconveniences and for the incompatibilities with .NET 8.0.3 and 8.0.4

---

If WingetUI is still not launching, do the following steps

1. Go to Windows Settings -> Apps -> Installed Apps
2. Uninstall the following packages (some of them may not be present on your machine):
   a) WingetUI
   b) Windows App Runtime Main
   c) Windows App Runtime DDLM 5xxx.xx.xxxx.x
   d) Microsoft Windows App Runtime Singleton
3. Download and install WingetUI from here: https://github.com/marticliment/WingetUI/releases/download/3.0.1/WingetUI.Installer.exe
4. Download and install this: https://aka.ms/windowsappsdk/1.5/latest/windowsappruntimeinstall-x64.exe
5. Quit WingetUI and return to Windows Settings
6. Uninstall the following packages:
   e) Microsoft .NET Runtime 8.0.X (x64)
   f) Microsoft .NET SDK 8.0.X (x64)
7. Install .NET Desktop Runtime 8.0.2 using the following URL: https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/runtime-desktop-8.0.2-windows-x64-installer

If the steps above do not work, please downgrade to version 2.2.0 by doing the following:

1. Navigate to C:\Users\<your-username>\.wingetui
2. Right-click the folder -> Create -> Text document
3. Rename the file to DisableAutoUpdateWingetUI. Make sure to remove the .txt extension from the file name.
4. Uninstall WingetUI from the windows settings
5. Download and install WingetUI 2.2.0 from here: https://github.com/marticliment/WingetUI/releases/download/2.2.0/WingetUI.Installer.exe

Explanation of the issue:

This issue mostly happens due to a bug on .NET 8.0.3 (hence the downgrade to 8.0.2) or for the Windows App Sdk not being installed properly. I am working to fix this issue, but since it is not directly caused by WingetUI, it is hard to fix it.

Unfortunately these steps did not work for me... WingetUI did not launch after installing in step 4, so I remove Desktop Runtime 8.0.3 (installed by WingetUI) and installed the linked 8.0.2 but still does not run.

Going back to v2 and blocking upgrades... this is sad because WingetUI 3.x DID work for awhile on these machines.

Can you please look at Event Viewer, under Errors, and see if there is any WingetUI entry?
