InstallShield supports the .prq files to define InstallShield prerequisites for installing required software components. The files can not be imported into the Requirements view to define system software requirements. You need to create your own requirement for .NET Framework 4.6 in the view. Also, you may want to consider evaluating InstallShield 2016 Express which includes the more recent built-in system requirements including .NET Framework 4.6 .
