Creating a upgrade .msi file
-
I have tried to find some information on the internet but can't seem to find any tutorials on this. Basically when someone install's my application I will have it check when they run the application to see if there is a update available. If there is a update available it will download and run the new MSI file. (This is all done). The problem I am having is when you run the new MSI file, I can not get it to actually upgrade the program. I have changed the Version number from 3.0 to 4.0 in the setup file and then select yes to update the ProductCode since I changed the version number. I have RemovePreviousVersions set at True and DetectNewerInstalledVersion to True. Am I missing anything or does someone know of a article that describes how to do this?
