Hi,

the major upgrade works properly, the old product is uninstalled automatically..., but the variable IS_MAJOR_UPGRADE is not defined.

I use this variable to display a message to warn the user and bypass some windows like the license text.

Why this variable is not defined?

Is there another way to detect major upgrade?

Thank you

Chris

IS_MAJOR_UPGRADE is set by the ISSetAllUsers custom action. Do you have this action in your sequences? (I've seen problem reports with this custzom action if you migrated to newer versions of InstallShield, but I don't have the details at hand)

IMHO the best way to detect a major upgrade is the property you specified in the Major Upgrade entry on the Advanced tab (by default InstallShield uses something like ISACTIONPROP1)

Indeed, I've migrated to newer versions and ISSetAllUsers was missing.
The problem is solved now by adding this CA to my project, thank you Stefan.

Concerning ISACTIONPROP1, I think it will be also set on Minor upgrade...
