@Barrie Anderson, Thanks for posting in Q&A.
For exe file, the way to deploy via Intune is via Win32. For Win32, the install commands need to support silent install. From your description, it seems the application does not support. So I think it can't be deployed via Intune Win32.
For your situation, maybe you can contact the app developer to see if the app can be installed via PowerShell script or others.
Hope it can help.

Thanks for replying, if i run the application as is, it simply loads up the installation process
the application is called DocFetcher (https://docfetcher.sourceforge.net/en/index.html)and the exe does not appear to support any switches to be used at command line, running the application in command prompt with any switch simply begins the installer gui as you expect when double clicking the file.
the aim is for me to add this to intune so the user can install this via company portal as the user is based remotely, if they try and run the application themselves it will ask for administrator credentials.
