Clickonce update install prerequisite

I have an application deployed using Clickonce to over 200 users, the application was initially developed and deployed with .NET 2.0. I have to migrate it to .NET 4.5.2, I set the prerequisites to check for "Microsoft .NET Framework 4.5.2 (x86 and x64)". I'm trying to deploy it as an update (which it is) but when I tested in on PC without the 4.5.2 I'm getting this screen:

System Update Required

Unable to install or run this application. This application requires Version 4.5.2 Full or other compatible .NET Framework

If the user use the installation URL created by Clickonce it is running the .NET 4.5.2 installer. Is there a way to make the update to launch the .NET installer automatically?

I was getting this problem because I was browsing to the manifest file rather than setup.exe. Something to watch out for.

Open Publish tab from the project properties, then prerequisites, then select the middel option as in the next pictures:
