Uninstall before Reinstall??

Hi again,

I noticed that if i reinstall an existing application using the same installer, it doesn't uninstall before installation.

However, if i reinstall using another build (different Revision code) it uninstalls, then reinstalls.

Can i code it in the way that packages with the same Revision Code goes thru an uninstallation process as well??

Sure, you could do that. Just read your setup's MSIcode - the prereqs section - and take out the test and/or condition for the previous version, to do the uninstallation always.
