In this article, I want to share a couple of tips on where to find and how to download the Win32 (*.intunewin file) application if don’t have source files anymore or you lost them.

There is no download button in the MEM portal, so I will show you a simple way how to access converted Win32 application files that you once uploaded to the MEM portal.
First, you need to assign the Win32 application to the user or device group. I would suggest you try this on a test device or preferably a virtual device that you can revert to snapshot, so you don’t mess up permissions because we will be changing them.

Now you can start fetching source files from the *.intunewin file.
These are the steps to take in order to locate and copy source files.

• IMECach folder – this is a standard location that is used to install applications by MEM. How these files get there you can find in my other blog “How to troubleshoot Win32 app on device? – UonCloud” 
• Set permissions – open Windows Explorer and change System permissions on this folder “C:\\Windows\\IMECache” this is why I would use a test machine.
  • Select Properties on folder -> select Security tab -> select Advanced

• • Select Change permission -> double click on System account

• • Remove these Basic permission -> Full control, Modify
  • Change Applies to -> This folder, subfolder and files
  • Have these Basic permissions selected -> Read & Execute, List folder contents, Read, Write

• • Set a checkbox -> Replace all child object permission entries with inheritable permission entries from this object

• • Accept Windows Security alert -> Yes (twice)

• Install application – now open Company Portal and install the application to fetch the source files

• Source files – after the application is installed check the “C:\\Windows\\IMECache” folder, and that’s where you will find already extracted Win32 application files, so this is where you can copy them out from the IMECache folder.

IMPORTANT!!! Do not change these permissions on production devices.

Another option is not to lose them initially, so you don’t have to go through this hassle.
We’ve built our custom portal APM where we keep all our application packages in a single place so that we always have the *.intunewin file accessible (AMP – Application Management Platform for Intune Applications (uoncloud.com))

Hopefully, you find this helpful and useful in case you need to access Win32 application source files.
