Setup project with autoupdate feature vs2010

Question

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.

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.
