Upgrade-related Serious Complication

Hey guys,

I have an urgent doubt regarding QuickPatch projects and minor upgrades. Let me explain my issue:

1. I have a Basic MSI project, say version 1.0 of my product.
2. I create a QuickPatch for the 1.0 installer (based on the MSI for 1.0). This QuickPatch is version 1.0.1 of my product, and can be removed.
3. I now am working on a new Basic MSI project, version 1.1 of my product.

I wish to enable upgrades in my 1.1 installer from versions:

Is the solution here to create two minor upgrade entries in my 1.1 project, referring to my MSI files for:
->1.0.1 (MSI built in the UpdatedImage folder)

Or should i create just one minor upgrade entry for:
->1.0, and this will take care of upgrades to 1.1 from both 1.0 and 1.0.1?

Please help me out here guys, I'm stuck here.

Thanks a ton.

A single minor upgrade is sufficient to upgrade your previous releases 1.0 and 1.0.1 to 1.1. You can created Windows Installer Package or even by updating Upgrade entry table in Direct editor of your 1.1 ISM will helps to upgrade all your previous releses to latest.

Ensure that in all the releases of your product you are maintaining same UPGRADE CODE
Product code also should be the same in all the releases as it is a Minor Upgrade
