Find a product is already installed during installation

Hi,
I have a product installed using windows installer. Now I am trying to
install another version of same product. I have option to remove the previous
installation by using "RemovePreviousVersions" property.

Is there an option to find my existing installation, and provide option to
uninstall it.

Thanks in Advance

Hello,

In MSI previous versions are removed with the RemoveExistingProducts
action. This action has to be scheduled in the InstallExecuteSequence.
For the right place, look here:

Use the Upgrade table to detect previous versions of your product. ->

RemovePreviousVersions is th Visual Studio implementation of
RemoveExistingProducts. There's no mechanism in VS setups to ask if the user
wants to uninstall the previous version. It just dies it.
