Hi @mmojadad,

Can you provide the logging information for the msi execution?

You can collect such information by using:

msiexec /i  yourfile.msi /L*v  c:\temp\yourinstall.log

Hello
I fixed it. I used MicrosoftProgram_Install_and_Uninstall.meta.diagcab based on advise on the following URL :

Thanks

I had another problem using the Windows installer which was seeing error 2503 followed by error 2502 in the event log.

If you encounter these errors it can be resolved by granting appropriate permissions to C:WINDOWSTEMP for the user.
