I have a WinForm Application done in Visual Studio 2012, Framework 4.5. I made the Setup Project with InstallShield. I need to install this App on PC that may not have Framework 4.5 installed, so I add Framework 4.5 as a PreRequisite. So far So good.
What I want is to Install the PreRequisite automatically, without asking my clients when they Runs the Setup.
Is that Possible?
Edit your PRQ to always install .net45 with no input. Here is a .net40 PRQ we use locally.
/passive has it show a progress bar, but you could just as easily do /q (no UI at all). The only problem would be a very long startup delay to your install which the user would probably interpret as "something is wrong" so I'd recommend keeping /passive.
InstallShield doesn't support this feature. The closest is to make the prerequisite mandatory. Another possibility would be to associate the PRQ to a feature to make it a "feature prereq" instead of a "setup prereq". This would cause Setup.exe to go right into your MSI and then defer the installation until after user interview.
