basic msi project : major upgrade, want not uninstall previous version

[Brieuc]

Hello,

I have a basic msi project, and I need to upgrade my product. And I need a major upgrade (version 10.0 to 11.0).

I read the Installshielduserguid.pdf, and the chapter "Updating Applications"...

Documentation :

If an earlier version of the product does exist on the target machine and the end user runs a major upgrade, they encounter almost the exact same installation experience as if they were to install the latest application on a clean target machine. The difference is that before installing its new resources, the installation typically uninstalls the earlier version from the target machine.

My question is simple, is there a way to create a major version, without uninstall previous version, but just replacing differents files ?

If yes, what should I do ?

Thank you.

Without uninstalling previous version, it is called Minor Upgrade. For their differences, please refer to Patching and Upgrades.
