Can't install - "To install this application you need either a Windows developer license or a sideloading-enabled system"

[superluig164]

I'm getting this error at the last step. I deleted the required files (AppxMetadata, AppxBlockMap.xml, AppxSignature.p7x, [Content_Types].xml)

I'm on Windows 11 22H2. What can I do to solve this?

did you install XAML 2.6?

[Masamune3210]

This has nothing to do with that

[superluig164]

Should I try to install XAML 2.6? I didn't notice that as a part of the instructions...

[Masamune3210]

If you have installed any vaguely recently updated apps with a UI from the Microsoft Store, I almost guarantee you have it installed already since its a standard dependency

[Masamune3210]

But you can if you want to make sure, it wont mess anything up. It will either install it, say that its already installed, or say that a newer version is already installed

[superluig164]

I'm still having this issue, anything I can do?

[superluig164]

Solved it. I hadn't deleted the p7x file.
