DesktopAppConverter can't convert exe

Question

I'm trying to use the DesktopAppConverter to convert an .EXE package into UWP compatible executable so I can publish on Windows Stores.

The exe package is compiled from Unity3D for standalone.

When I use the convert command I get an error.

DesktopAppConverter.exe -Installer .\eve.exe -Destination .\Converted
-PackageName "eve" -Publisher "CN=C9839D08-E518-4B7C-BA6C-FCA61493C7F3" -Version 1.0.0.0 -MakeAppx

C:\Program Files\WindowsApps\Microsoft.DesktopAppConverter_2.1.4.0_x64__8wekyb3d8bbwe\DesktopAppConverter.ps1 : Exception calling "Compile" with "0" argument(s): "Reference

I would appreciate the help , I tried looing online but couldn't find a solution.

Answer 1

The DesktopAppConverter is Microsoft's first try at building a tool for converting older packages to MSIX/APPX.

They deprecated it and instead released the MSIX Packaging Tool. I included a link that teaches you how to use this tool to convert your package, give it a try.

If this still does not work, you can use the free Express edition from Advanced Installer. This was released in a partnership with Microsoft before they built their own solution (the MSIX Packaging Tool).
