Troubleshooting Win32 app deployments

Check the detection rule first

A surprising share of reported failures are successful installations with a detection rule that does not match reality. Verify the exact path, registry value, or product code on a device where the software is already installed.

Read the management extension logs

The Intune Management Extension writes several logs for Win32 app activity. Start with AppWorkload.log for deployment events and AppActionProcessor.log for detection and applicability checks. Use IntuneManagementExtension.log for broader agent check-ins, policy processing, and reporting.

C:\ProgramData\Microsoft\IntuneManagementExtension\Logs

Install context and dependencies

• Installers running as system should not rely on the signed-in user's profile or mapped drives.
• Dependencies must be detected or installed before the dependent app can complete.
• Requirement rules and assignment filters determine whether the app is applicable to a device.
