What I am trying to do is as follows:
I have an msi file, with our product installation.
we have an "outside" version, which we put on the web, and a "inside" version for internal use.
once in a week we built a new "internal" kit. by that we run all our images, and the msi should replace all images, even the ones that were changes only by modification date.
My problem is this -
How can upgrade the installation, so it would replace all files, and add components/files/etc.
I tried to change the ProductVersion, and the ProductId, but I got a message saying that "the program is already installed on this machine..."
So that did not work. what would?
And for the web version, every time we built a new kit, we would like to send the users a new msi, and that the new msi would run, and replace/add everything.
How do I do that?, please help figure this out, cause I really can not.
Thank you in advance...
