Hi,
Can you try installing MS-MPI while Process Monitor is running, and send us the logs?
You can install Process Monitor at https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx. When you start it, and filter the capture to "Process Name is MsMPiSetup.exe", it will log when the setup is trying to access a file/reg
which cannot be found, and we can figure out what the issue is.
Thanks,
tuba
