Skip installing a package if there is already a newer version of it
Currently, InstallShield aborts installing when it finds that a newer version of a package is already present. It is done to prevent downgrade. However, is there a way to make the installer skip installing the package and continue the installation process?

Continue to do what?
If your package is a downgrade, do you want to disable downgrade prevention? If so remove the upgrade item called "PreventDowngrade" \ "ISPreventDowngrade" or the associated Error CustomAction of the same name.
If you just want the installer to run to completion without showing an error message, but actually do nothing. Well that is really quite a complicated set of changes that is required and quite ridiculous too. I would never recommend attempting this.
