Hi,
I just downloaded AI 6.7. I see there is an uninstall previous versions custom action, UninstallPreviousVersions. This is just what we need; the new installation of our product should uninstall the previous version. I can create the custom action, but I don’t see how to call the custom action. It needs to be called at the very start, before it is decided to modify/remove the previous version. How do you call UninstallPreviousVersions? The PrepareDlg does not allow adding actions. If I right click on “InstallExecuteSequence” the “uninstall previous versions is grayed out. What’s the trick?
Thanks
Bob
