Uninstall Winget Packages Not Working

[dlmichener]

When I uninstall an application installed from Winget, UniGetUI says that it installed the package successfully. But if you refresh the list of installed applications, you see that the target application is added back to the list.

If you look at the command line log of the uninstall operation, you can see that it displays the winget command help text, telling me that it did not like the command text that UniGetUi sent to winget for the uninstall operation.

I am using the latest version, 3.1.5, on Win 11.

Can you please share the UniGetUI logs?

I see this error at the end of the log file:

Oh, I see what the issue is.

Could you please try UniGetUI 3.1.6-beta2? It should have this issue fixed

[dlmichener]

Using beta2 allowed me to run the uninstall scenario that had been failing for me previously. Afterwards that application was no longer showing as installed in UniGetUi or in Windows.

However, the UniGetUi log did have the following "fatal" error listed at the end after I ran the uninstall:

The thing is that this issue is not directly caused nor fixable from UniGetUI, but a simple override can do the trick, and this is how it is "fixed" on UniGetUI. Yet, the error still shows on the log for clarity.

[dlmichener]

Understood. I just wanted to be sure it was not something new for you.

Thanks again!
