What is the best best way to download and install msi\exe

Question

I need to install drivers to my clients silently. Now, I have some issues:

1. I don't want to install them directly from the internet using Process.Start("www.......msi") beacuse it goes really slow. I want first to download them to the computer and then run a winform application to let the client choose which driver to install. I tried the VS Installation but I couldn't figure out how to download all the "c:\Program Files" and NOT to the "Program files (x86)" in case of a windows with 64 bits. And I couldn't figure how to launch the winform app after the download complete, using the "custum action" didn't work.

2. I have different drivers for x86 and for x64, and I need to download to client's computer the drivers that he needs, how can I do that?

3. I have both msi and exe drivers, how can I install the exe driver silently?

If you know some third-party application I would be greatfull, this could be the best option for me!

Found the answer in Visual Studio 2012 with the InstallShield and some programming work in my code. Thank you all :)
