Using visual studio,
Microsoft Visual Basic .NET 69586-335-0000007-18957
I need to provide an update to a program that is currently running fine at a client. They did the installation via an msi file I built. But the last time I tried to provide just an update, the install (on Windows 2000 and XP machines) required a complete deinstall of the original program. Because the changes are very minor, I know that just copying over the *.exe will work fine, but I want to make it more foolproof so they can just apply the msi as if it were a patch and not a completely new program. What's the best/correct method to do that?
