Major Upgrade does NOT uninstall the Product before install the new one

[forcet]

The upgrade didn't remove the old product..

I checked IS_MAJOR_UPGRADE property, the value is "Yes", which means the installer is performing the major upgrade, but the old product has not uninstalled when the new install starts..

Thanks in advance...

Check further in the log, around RemoveExistingProducts, to see if it tells you anything else. One reason I can think of offhand is if the product was originally installed per-machine and the upgrade is running per-user.

Yes!.. the "RemoveExistingProducts" action is missing from execute sequence, weird... I added it back, then it worked... Thank you ..
