Adding Support of .NET Framework 4.6.1 Prerequisite into InstallShield 2015 in VS2015

For most of .NET developers, you might need to create a installer package for your developed application and you might be using InstallShield. One of the configuration that you would do is setting up the .NET Framework requirement for your project.

In VS2015 with InstallShield 2015, you will found the pre-defined package for the requirement of .NET framework is only up to “Microsoft .NET Framework 4.5 Full package”. I am going to show you how to add the package into InstallShield 2015 for the “Microsoft .NET Framework 4.6.1 Full Package”.

Below is the text that can be used to create your own .prq file for the Microsoft .NET Framework 4.6.1 Full Prerequisite.

  • The Conditions are set for 64bit only, Windows 7, Windows 8, Windows 10.
  • The download location is good as of 10th March 2017. No telling how long it will last. If the download does not work any more, you would download the offline installer from and then copy it into “C:\Program Files (x86)\InstallShield\2015\SetupPrerequisites\Microsoft .net\4.6\Full” folder
  • If you received similar error as below
    “An error occurred streaming ‘\4.6\Full\NDP461-KB3102436-x86-x64-AllOS-ENU.exe’ into setup.exe”
    You could try to run the InstallShield or VS in Admin mode.

For those new to making a Prerequisite .prq file:

  •  On your desktop create a new text file.
  • Rename this file “Microsoft .NET Framework 4.6.1 Full.prq”
  • Copy the above text to this new file. (Between the +++++)
  • Move this new file to folder C:\Program Files (x86)\InstallShield\2015\SetupPrerequisites
  • Open any InstallShield project
  • Go to the Installation Designer tab > Application Data > Redistributables
  • The list should now contain the new entry “Microsoft .NET Framework 4.6.1 Full”
  • To the right of the list it will say “Needs to be downloaded”
  • Right-click on the item Microsoft .NET Framework 4.6.1 Full.prq and select Download Selected Item…
  • This downloads the 66 MB file to C:\Program Files (x86)\InstallShield\2015\SetupPrerequisites\\4.6\Full\

You should be good.

To edit any of the Conditions:
Right-click on the item Microsoft .NET Framework 4.6.1 Full.prq and select Edit Prerequisite

To Support 32bit and 64bit:
You could remove the “Bits” or leave the value of it to be blank in the above sample, and that will work for both x32 and x64
