Remove All Versions before installing using VS.Net setup project

Hi,

If I use a combination of RemovePreviousVersions and UpgradeCode I can remove any previous versions of the app being installed - so 2.0.0.4 will be uninstalled when I try installing 2.0.0.5 - but how do I uninstall 2.0.0.5 when I install 2.0.0.4 - looks like the two properties mentioned above do not help while doing that. The target really is that only one version of the app should be installed at one time -

Any help will be appreciated.

Thanks, Shilpi

Hi Shilpi,

You can set the DetectNewerInstalledVersion Property to True in your setup project. This way, if 2.0.0.5 is installed and the user tries to install 2.0.0.4, Windows Installer will prompt a newer version is already installed and the current install session will end. The user must manually uninstall 2.0.0.5 to downgrade to previous versions.

Jie
