I am trying to upgrade an existing setup, but unable to build. The error I am getting is 7155.
Upgrade item with Action Property ISACTIONPROP1 conflicted with another item and has been dropped.

Also I am getting a warning 7211.

Please help me with this.
I could not find online help.
Thanks.

It would be nice to know what fixed this issue. I'm having the same issue and can't find help for it.

I'm also having the same issue. I had one Major Upgrade item that was set to upgrade all products with the same upgrade code.

I then added a second Major Upgrade item to upgrade products with a different upgrade code (we acquired a company and I need to uninstall their product before installing mine).

This is when I got Error 7155: Upgrade item with Action Property ISACTIONPROP1 conflicted with another item and has been dropped. This may result in conditions referencing property ISACTIONPROP1 to behave incorrectly.

I removed the second Major Upgrade and it worked again. But I really need to be able to upgrade the other upgrade code. What am I not doing right?
