Preparing to Install a Visual Studio Project

I created a VSTO PowerPoint add-in in Visual Studio. To distribute this to users, I created an InstallShield setup project.

After creating this project, the installation and add-in works fine if I use this option to download the required prerequisites from the Internet.

However, when I use the option to extract prerequisites from Setup.exe, it doesn't work: the add-in itself is installed, but there are no prerequisites.
I know the preconditions are included in the setup because without them Setup.exe is about 2MB, with the preconditions it is about 290MB.

I have two prerequisites selected in the Prerequisites view:

In the Releases view under the Setup.exe tab SingleImage InstallShield Prerequisites Location is also set to Extract from Setup.exe .

But the installer just won't install .NET Framework 4.5 (usually present on user systems if needed) and VSTO Runtime, even if I included it in the installer!

Any help is greatly appreciated.
