This problem is very strange and I donno. where can dig into.
I'm creating a windows setup project and with no custom installations. I have just used the options and properties given by the project.

Here my problem is, whenever I try to install my application it should not ask for the earlier version existance and should remove the previous version behind the scenes.

For achieving the above funtionality I've utilized the properties of the Setup project - "ProductCode" and "RemovePreviousVersions".

Everything works fine except, on each installation after the "ProductCode" change results in another entry in Add/Remove programms.

Please give me some pointers how to resolve this ??
