Missing roles when installing

When 

Installation of Pronestor Display fails with message that ASP.NET role or STATIC CONTENT are missing. 

Why 

For some IIS installations the required pre-requisits are enabled but for some reason the installer can't verify this - and the installation fails.

How

Open a command prompt and run the installer with the following parameters in the "Pronestor Display" download folder:

msiexec /i proNestor.Display.Setup.msi /l*v logfile.txt BYPASS_PREREQUISITES=1
