Running updated MSI does not have any effect

I created MSI using InstallShield and installed a package. Next step I created an update. On the property page of MSI file I had to setup the same "Revision number" as in the original one because otherwise I get message:

Another version of this product is already installed. Installation of this version cannot continue. To configure ore remove the existing version of this product, use Add/Remove Programs on the Control Panel

But once I double click on new MSI the system actually runs an old one saved in c:\windows\installer. Is there anyway to force the system to run the new MSI file? (I changed the version number, but kept all other UIDs the same)

BTW when I delete "LocalPackage" entry in registry then the system runs new MSI.

Now I tried to create new installation. I changed major version and also Product version. I get error:

A newer version of this application is already installed on this computer. If you wish to install this version, please uninstall the newer version first.

The thing that defines whether a product is installed is the ProductCode. The revision number of an MSI file is more commonly known as the PackageCode. Both the PaCckageCode and the ProductCode must be different for creating a major upgrade.

I wouldn't advise deleting the local package MSI. That's used for maintenance and uninstalls.
