I have create a setup project for windows application. When I trying to
install the project on target system..It is detecting the older version and
showing an error message
              '"Another version of this product is already installed,
installation of this version cannot continue. To configure or remove the
exising version of this product, use Add/Remove program on the Control
Panel."

             Then I have to remove the project from control panel and
install again. With out doing this process. is there any way to remove the
older version of the project automatically and install the newer version ,
or , upgrade to the newer version of the project.
          I wan to install the project by forcing even older version of the
product is exist. How can I do this..?
        Any solution please..

Set the setup project property "RemovePreviousVersion" to false.

If you want your new setup to automatically uninstall the old version:
1. Increment the setup project's Version property. It will prompt you to
change some codes, say yes.
2. Set RemovePreviousVersions to True.

This requires that the new version be the same per-user/per system type. A
Just me will replace a Just me and an Everyone will replace an Everyone, but
one won't replace the other.
