Hi,
Thank you for posting in Microsoft Q&A forum.
1,It seems like that the MP server is not functioning well. If possible, please install the MP role on a new server to see if it works ok. It is important that the SCCM client agent has to be removed completely from the server before you install or uninstall MP role.
To troubleshoot 1603 errors in Windows Installer, please examine the verbose MSI log file mpmsi.log for details. Search for "return value 3". The cause of the problem should be logged just above this line.
Please refer to:

2,Similar threads for your reference. You can try to install the latest update on the MP server.

Thanks for your time. Have a nice day!
Best regards,
Simon
