We're deploying an upgrade to our current system, upon launching the installer, the program/launcher gives us a message: "The application requires .Net Framework 4.5. Please install the .Net Framework 4.5 then run the installer again."
Is there any other way to install/upgrade our current .Net Framework installed? Is there any alternative updates to consider.
We need your great minds here.
