Web Based Menu To Open Windows Applications

Hi All

Apologies if this is the wrong place for this question.

Just wondering what people have done to create a user interface ie a menu with buttons, which when clicked, open up a windows application, programmed in vb.net.

This must open up the latest application and therefore allow developers to update the application without a cross over between users locking a file.

Hope this makes sense, just want to know what methods people have used. I know you can publish and let users know when an update is available, but would prefer a menu.

Thanks in advance
