You can generally do this using your Deployment Package.  3rd party packagers would be better at this sort of thing, like Setup Factory:

Thank you for your link. but unfortunately i cannot use 3rd party tool.

Is ther any way of doing it in VS 2010?. I found this post but still not able to uninstall automatically.

Hi,

Based on my experience. There's some something when creating the Setup project in .NET.

1. make sure the UpgradeCode is same as the old version.
2. check the RemovePreviousVersions Property to see if it was set Ture.
3. make sure the InstallAllUsers property is same as old version.
4. Also check the Version property,  you need to increment assembly version for each assembly that has changed since the previous deploy.

More information and workaround you can check these links:
