And your setup itself is also signed with a trusted signature? According to the document linked in the original post: If the security service is unable to make a confident prediction about the app, then Smart App Control checks to see if the app has a valid signature. If the app has a valid signature Smart App Control will let it run. If the app is unsigned, or the signature is invalid, Smart App Control will consider it untrusted and block it for your protection. And also: "I'm an app developer, how can I get Smart App Control to not block my app?" The simple answer is, sign your app with a valid certificate. So this might be a bug in the pre-release version of SAC. Please give feedback to Microsoft: In Windows, go to the  Feedback Hub. (from the Start menu or press Windows key + F). When you get to  Step 2 - Choose a category, select  Security and Privacy  -  Smart App Control. ... View more

Here's a quote from documentation https://docs.revenera.com/installshield26helplib/helplibrary/UpgrdngToIS2011.htm#gettingstarted_3084197908_1170547: Deprecation of InstallScript Objects InstallScript objects have been deprecated in favor of InstallShield prerequisites. In a future release,   InstallShield   will no longer be able to create or consume InstallScript objects, and no predefined InstallScript objects will be provided. Furthermore, the Merge Module Holder Object will not be available. The recommended alternative for InstallScript objects is InstallShield prerequisites. You can use the InstallShield Prerequisite Editor to begin creating your own InstallShield prerequisites so that you are ready to use them once the InstallScript object technology becomes obsolete. You can share these InstallShield prerequisites among InstallScript, InstallScript MSI, and Basic MSI projects. Maybe your project was created with an older version of InstallShield and therefore includes the merge module holder object. You could try to copy the object (not the merge module) from [ProgramFiles]\InstallShield\2020\ObjectsPro\Merge Module Object ... View more

Under Upgrades > Upgrade Windows Installer Setup there should be an entry ISPreventDowngrade which InstallShield puts there by default to prevent this problem. Is this missing in your project? (Maybe your project was originally created in a much older version of InstallShield thata didn't have this entry).  If the entry exists and never altered (you don't have to adjust anything there, it all happens automatically during build) then make sure that the UPGRADECODE has not changed between these versions and that the version number has been incremented in any of the first three fields (not just in the fourth. ...
