I have created a setup project in visual studio. It works fine, now when i make some changes, create new setup file and then try to execute it. It gives me this error.

enter image description here

I don't want user to bother with this step. I want it to update the application or uninstall it first and then install new version.

How could i do this.

Kindly guide.

Windows Installer automatically uninstalls the old version if you increase your package ProductVersion and change the ProductCode. This can be done in the project Properties pane.

If you don't do this, you need to uninstall your old package manually using the Control Panel applet.
