You created MSIs from the same project, so they have the same GUID and probably other details (name, version etc.) - making them essentially the same installer from an MSI perspective, hence the error message.

What are you trying to acheive? Do you need two MSIs, both of which will install in the same machine?
You need to change details to make it unique if that's the case.

>You need to change details
As m' learned friend says, if they're compiled from the same project, why would you expect one to replace the other? At the very least you'll need to change the ProductCode and PackageCode.

Thanks for your reply.....

I want to install the updates (minor update).that's why I tried with same product code.If I change product code, multiple entries are there in add or remove programs. Just I want to overwrite with existing installer...

You need to take care also if you are using a template to regenerate a new GUID each time

You need to consider whether installing with REINSTALL and REINSTALLMODE properties set to your requirements will fix this. Well documented in the help file MSI.CHM.
