Thank you for posting in Microsoft Q&A forum.
The important log in case of client installation in the agent is the ccmsetup.log and clientmsi.log these logs are present in the location C:\windows\ccmsetup\logs.
When we start troubleshooting client push installation the first log we need to check is ccm.log in the server logs(%ProgramFiles%\Configuration Manager\Logs), from ccm.log you can see the start of the request made to the client and you can verify if the ccmsetup.exe service was able to successfully run on the targeted client machine.
For more details, we may refer to this article:
