I use the IS MSI project of InstallShield X. My project includes the Patch option...
Each time when I Build a patch, I received the following error:
"The setup needs to perform a Major Upgrade of the previous setup specified. However, the Upgrade Code for the previous setup {xxxxx-xxxx...} is not in the upgrade table. An upgrade will not occur. Val003"
I performed the Resolution "F" of Q108857, but it's has not solved this problem...

Furthermore, the required Upgrade Code appears in the Upagrade Table...

I don't understand what a problem?
somebody can help me???? Please!!!!
