So, I've repackaged Firefox 2.0.0.2 with AdminStudio to make it easier to deploy. As far as the basic installer goes everything is working great. However, I'm trying to make an installer that will both install firefox 2.0.0.3 or upgrade from an older version if necessary.
Right now, when I try to install 2.0.0.3 over 2.0.0.2 I end up with 2 different firefox icons in the add/remove programs and removing both of them is the only way to completely firefox. Only removing one leaves me with which ever version I did not remove. ie I remove 2.0.0.3 I get 2.0.0.2 and vice versa.
I was able to find some information on msi upgrade codes, but I have been unable to get them working correctly, any help is greatly appreciated.
