Problem:

This article documents how to install silently Micro Focus patches in the shape of .msp files

Resolution:

The Windows Install utility msiexec is used to install .msp files. Running:

   msiexec /?

getting back the list of options that msiexec can use.

The command line tested here for Micro Focus .msp files is:

  start /wait msiexec /qn /l*vx myfile.log /p myfile.msp

where /qn means that no user interface will be presented

and  /l*vx myfile.log means that everything will be logged in myfile.log with verbose output and extra debugging information.
