Hi,
Thanks for your reply.
This can occur if a previously failed installation of the Configuration Manager client left behind an IPI installer file (.ipi) in the %systemroot%\installer directory on the target computer.
Search for *.ipi files in the %systemroot%\installer directory on the target computer and temporarily move them to a different folder. Next run the setup of the client installation again and it should complete successfully.
Please refer to: MSI: Configuration Manager Client is not installed
Thanks for your time. Have a nice day!
Best regards,
Simon
