How would you go about converting a .exe to an MSI to use in Intune Applications?

Question

Hi,

I've read up on different methods for converting .exe's to MSI's such as:

• Using Advanced Installer
• Using WiX toolset
  • Still unsure on how to go about this?
• Other third party tools
  • EMCO MSI Package builder

However, it seems with these package builders they aren't fully "FREE" and give a trail run of using the application. What I'm looking for is a Microsoft recommended and "FREE" way of converting .exe files to MSI's.

If this isn't the case I know we can package up applications as .intunewin files and add these as Intune Applications but, the use of MSI would be least messy and we would only need to add the updated MSI to the Intune Application every month or so?

If anyone could also recommend the best practice for updating Intune Apps that are package installed/MSI installed that would be great.

Also, if anyone could answer how/when Microsoft Store Apps send out updated versions, that again would be useful.

Thanks!
