Seems that there are some remnants from previous agent version is installed on the client machine. Please open a case with support.
It is looking for MFEagent.msi file during installation. try below 2 options
1. Run Frame package file with forceinstall command : /install=agent /forceinstall
2. If above force install command is not working than get old framepackage file (Previous running version of McAfee Agent) if you have saved somewhere and extract on machine desktop.
Run the new framepackage file and once you get popup for MFEagent.msi than navigate to folder which has been saved on desktop (it contains MFEagent.msi file). Select the file and click on OK.
Try above option and let me know results.
