MSI Installer Problem ... any1 help?
I've created a msi installer for my application. I can installed the app in a clean PC, but the second time i install the apps, it says the current version is exist and prompt me to uninstall the previous version. Is that anyway to upgrade my client without uninstall the app with msi installer? I've try to change the version and product code but seem no effect. Any1 got idea on this?
