Hello, dear All
I have the following problem: i have a .net (C#) app and a Windows Installer project to deploy it. Now i want this Installer project be able not just to install the app onto a 'bare' client machine, but also to check if some previous version of the app has been already installed and update it if necessary.
At first glance, this problem seems as very common and easy to find solution for, but, surprisingly, Google says nothing about it. If somebody knows at least where to look for a solution - i'ld be very grateful for a help.
