JE557456 asked a question.
Can I build a 64-bit InstallScript MSI Project on a Windows 7 PC and expect it to work correctly on Windows 10?
I am just now learning how special the %windir%\system32 folder is, not just on Windows 7 but even worse on Windows 10.
Currently the build process I am using to create install kits is running on build machines that are based on Windows 7. Since Windows 10 functions differently, I am wondering if perhaps I will have almost insurmountable issues when that install kit is targeted for a different OS version, specifically Windows 10.
Yes, you can. The Template Summary property determines whether an .msi package is a 32-bit package or a 64-bit package, not operating system where currently installshield is running. You can refer below link for more details

OK. I have the template summary set to "x64;1033". That's the way it has always been. And yet it seems like uninstall doesn't just work correctly. Install seems to work fine.
This is with InstallShield 2018, not R2, not 2019. I don't know. Maybe it is just a bug. I certainly have found more than I would have expected of those. Working around the bugs is getting to be quite annoying actually.
