My original installation program is a Basic MSI project (Version 1.0). I am creating a minor upgrade installer now (which is Version 1.2), and the only thing that has changed is the application (a minor change in the code) and some image files. In the installer, I went to the Upgrades view, created a minor upgrade item, and pointed to the previous Setup.exe (for Version 1.0). I also changed the Product Version and the Package Code.
If there is no previous installation, the installer works fine, and version 1.2 of the application is installed with the new image files. However, if the previous version is present, the new image files will be installed, but version 1.2 of the application will not be.
I've been racking my brain trying to figure out why. Any ideas?
Thanks for reminding me about the log file. I forget about it sometimes.
I found the problem. In the log file it says that it won't overwrite my application with the new version because the "...existing file is of an equal version".
