download site

[sohel1]

I have a site set up already, but it's not exactly what I want. It currently is set up so individual files can be downloaded, but Product 1, an application, has 2 files associated with it (one is the application, the other is an autorun install file); Product 2 has about 16 files. I would like my client to log in (so I know who is downloading what), then click on a download button for Product 1, and both files download in 1 folder to client's desktop, and even install automatically. Product 2 cannot self install, but as before, I'd like my client to log in.
