/?,-?,/h, or--helpExtract the installer files to locate their documentation.
Search vendor forums/support sites using "command line" terms.
Considerations
Apps must support silent install
Per-user MSI’s are not currently supported
Not all newer version of applications will automatically remove the existing version. Consider using the Patch My PC Uninstall-Software.ps1 community script as a Pre-Install Script in that scenario
Putting the Architecture in the DisplayName forces detection to look in the 64bit Uninstall ARP key - example: x64 or 64bit or 64-bit
Apps need a valid DisplayVersion for detection. For example, 1.00-00e.2 is not a valid version number
Test the app installs okay as the SYSTEM user using PsExec. Intune will install apps in the SYSTEM context and this may affect installation and/or detection.
