Packaging an .exe file to MSIX and signing it

I have developed an application and want to publish to the microsoft store. I have tried using advanced installer but unless I pay $500 I cannot publish it i think using the trial version? I have also tried using MSIX Package (Windows) but then I need to digitally sign it, and then I can't add logos and etc. I also do not know how to get a certificate and convert it to .pfx format for this to work.

Honestly, this process has just made me want to stop, which is unfortunate. So I am trying to find a service or someone that I can pay to package my .exe app to an MSIX, signed and everything so that I can just upload it to the store on my account..but I cannot find anything on google.

Does anyone know of a service, or even a better application that has better guides for MSIX packaging and signing? Advanced Installer is pretty extensive, but their guides are based on MSI, not MSIX. Not worth paying $500 for when they are not even current with Microsoft Stores required format.

FYI - to get a useful answer around here it helps if you place specific questions (i.e. split your question into multiple ones, like: Do I need to digitally sign an application for the MS Store?; how do I add logos...?)

Back to your problem. I work on the Advanced Installer and I will try to give you some advice to help clear a part of your problems.

  1. First of all, to publish an application in the Microsoft Store you don't need a certificate. As explained in our guide, in your Store developer account you will find a package identity assigned to your application, here is an example:

enter image description here

The value that starts with CN=... must be copied and pasted into your Advanced Installer project, on the Package Information page, under the ID field. Make sure Digital Signing is disabled in your project. (You need to digitally sign the MSIX only when you deploy it outside the MS Store)

This identity will allow the MS team to certify you as the owner of the application. Once Microsoft approves your application submission, the MSIX package you upload will be signed with a Microsoft digital certificate. All MSIX packages uploaded in the store are signed by Microsoft.

  1. I don't know how complex your application is, but most apps can be packaged with the free Advanced Installer Express edition. Have you tried that? The commercial editions include additional features, but you might not need them.
