My project is finished and I want to send it to the Microsoft store.
I’m trying to sign an exported Universal Windows Platform app (The project is with Godot 2.1.4)
I’ve created a certficate as described in:
(I had to change the first command with CN=publisherName in it, in stead of publisherName, for the command to run)
In the final stap however, Signing the package, I get an error after the following command:
SignTool sign /fd SHA256 /a /f MyKey.pfx /p paswordXXX exportApp.appx
Done Adding Additional Store
SignTool Error: This file format cannot be signed because it is not recognized.
SignTool Error: An error occurred while attempting to sign: exportApp.appx
Number of errors: 1
Can someone give any advice please? I would like to also publish my app to the microsoft store.
I’m facing the same problem with Godot 3.0.6. Did you find a solution?

No, I did not put any extra effort in this since the windows executable export works fine, but I would be delighted if I could publish to the MS store, I pay the fee for having another project on there that was made with another tool.
I do have got myself more documentation on Godot in the meantime. If I find a solution I’ll post it here.

I’ve got my Godot 2.1 app published to the microsoft store with DesktopAppConverter. You can convert windows executables to packages for the windows store with this.

It was a bit of work, downloading a base image and windows kit, installing windows features. It had to be done on a windows 10 pro.
When things were set up, it was executing a DesktopAppConverter.exe command where the Desktop App Converter GUI helped me for generating that command, you can use it for free for a limited time.

After using DesktopAppConverter.exe you can change things in AppxManifest.xml, change icons and use MakeAppx to repackage with the updated settings and images.
Satisfied that I got into the microsoft store, the only downside with this workflow is that the user needs adminstrative privileges to install the app I read somewhere.
Here’s my app on the microsoft store:
