It is considered the "best" solution for this specific scenario because it eliminates the need for complex workarounds like virtualization or dual-booting.
Rename them to SETUP.EXE.OLD and _SETUP.DLL.OLD just in case you need to revert.
Using a custom 32-bit generic installer replacement is the cleanest, most efficient way to bypass this limitation without setting up complex virtual machines. The Core Problem: Why InstallShield 3 Fails installshield 3 32bit generic installer best
One of the greatest frustrations with modern installation tools is their reliance on the Windows Installer service. If that service becomes corrupted, many modern installers fail. The InstallShield 3 generic installer operates entirely independently. It unpacks compressed files, copies data, and writes registry keys using its own routines.

If you're looking to create an installer with InstallShield or use one, here are some general steps: The Core Problem: Why InstallShield 3 Fails One
