How to package a .exe file into a Appx or msix

  appx, msix, windows

I have an exe file that works on two different computers. I tried windows certification, it also works. But when I transform the exe file into msix with MSIX packaging tool and I test I am told that it does not work. I am unable to test the msix file on my computer as well. What is the best way to turn exe to msix or appx?
