InstallShield 2019 Upgrade
We recently upgraded our InstallScript MSI install from InstallShield 2016 to InstallShield 2019 R3 version 25. The upgrade went without error, however when running our install, nothing happens. Looking at the setup exe log reveals a "general error" is occurring. I see no more information in the Windows Event logs or elsewhere. How can I further troubleshoot this error?

Re: InstallShield 2019 Upgrade
Comparing my setupexe log from the failed install built with 2019 to a functioning install built with 2016 reveals the setup is failing to extract and locate ISSetup.dll. Any ideas why this could be occuring?
