Auto install flash player to the client where the flash.exe was located on serve

Good day!
I created an intranet site for the company and it is on the server, so the staff can view it. My webpage consist of flash for the viewing of images. The problem is the client who can view my webpage has no flash installer or totally no flash installed on their computer. Actually I have a flash.exe or flash installer in my server. I want to happen is when they view my webpage there is a pop up message for the auto install of flash installer and once they click automatically the flash would be installed. I mean the location of installer in the server they can catch? Is it possible?
Honestly, I have no idea about it. I have a lot of idea and questions in my mind on how the client can have the installer through pop up or any way.
Thank you
