Hi, I have a program that downloads a setup file and then executes the setup file. I've updated the installer several times to do new things, but windows seems to use the previous version of the installer that was used. I don't know why either.

Say I have the installer have a message box that says "Number 1." I install that application. Then I download a new version of the installer that's supposed to say "Number 2." It will still say "Number 1" unless i uninstall the application completely and then run the new installer.

I'm updating my installer version number for each of these. any ideas?
