@Rijo Joy, Thanks for posting in Q&A. For the error code 0x87D300C9, it tells that process execution was in progress when Intune stopped monitoring the process. The issue usually happens when the process gets stuck during execution. With the application, it may happen due to corrupt installation, incorrect command line arguments, or executing installation without silent switches.
To troubleshoot the issue, please manually test the install command of the app on one device to see if it can be installed successfully.
- Download and install PSExec tool to run with system account.
- CD to PSTools directory
3, psexec –i –d –s cmd.exe to run cmd in Ntauthority\system context
4.whoami to check running context
- Switch the app location and run the app install command we configured to see if the app can be installed silently
Please try the above suggestion and if there's any update, feel free to let us know.
