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?

Still the same error in Event Viewer... access denied

Didn't work for me sadly. Currently downgrading.

I'm experiencing this bug too, on this machine. I'm on Windows 11 Beta on an Intel Core 8th Gen with an iGPU. Anyone else with the same/similar config?

[jdrch]

Issue persists after updating to Microsoft .NET Runtime 8.0.4 (x64). Strangely, only the above machine is affected.

[gleib]

Same bug. WinGetUI was working fine prior to the following upgrades today:
2024-04 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5036893
2024-04 .NET 8.0.4 Security Update for x64 Client (KB5037338)
All prior Windows 11 upgrades had been performed.

Error in Event Log --> Windows Logs --> Application ...
Windows App Runtime
ERROR 0x80070490: Bootstrapper initialization failed while looking for version 1.5 (MSIX package version >= 5001.70.1338.0)

Fix above did not work.

[jdrch]

@gleib Which Windows 11 channel are you on: Beta, Canary, or ... ? Asking because my non-Beta, Stable Channel Windows 11 machines are unaffected.

[gleib]

Interesting. Not participating in Windows Insider Channels on this machine BUT do have "Get the latest updates as soon as they're available" option set. May try rolling back this latest update and see what happens.

[jdrch]

@gleib I have that option enabled too!

[gleib]

Decided to proceed with upgrades using winget in the command line. Among the listed upgrades ...
"Microsoft Windows Desktop Runtime - 8.0.3 (x64)" with an indication that 8.0.4 (x64) was available.
Did this upgrade among others (specific user apps, not system components), then did a BIOS upgrade and re-booted.
Following re-boot WinGetUI was working!

Hello,

Please test this custom build and let me know if it works: https://drive.google.com/file/d/1NO8jhMDBPmMGvlnaW5MXv5vjYjvmFJLa/view?usp=sharing

Thanks!

Hello, everyone,

WingetUI 3.0.2 has been published. It fixes

• Crashes with .NET Sdk 8.0.3 (no launch at all)
• Crashes with .NET Sdk 8.0.4 (Cannot locate resource from 'ms-appx:///Microsoft.UI.Xaml/Themes/themeresources.xaml)
• Crashes with the App Sdk (This app requires whe Windows App runtime) when it was already installed
• Crashes when elevating WingetUI from non-admin users

WingetUI 3.0.2 can be downloaded directly from here. If the crashes persist, please reply here and I will reopen the issue.

[gleib]

As noted above ... my WinGetUI installation (3.0.1) started working when discovered and updated "Microsoft Windows Desktop Runtime - 8.0.3 (x64)" to 8.0.4. That said, installed WinGetUI 3.0.2 and that is working fine as well.
Thanks!

[jdrch]

@marticliment confirming that WingetUI 3.0.2 resolves the issue. Thanks very much!
