如何使用VS 2015的InstallShield LE显式定位x86环境

Question

Since the "default" Setup-Project-Type is now longer officially supported by Microsoft in VS 2015, i'm trying to deal with InstallShield LE 2015 - delivered with VS2015.

I have created an Outlook AddIn, which i want to deploy on x86 AND x64 machines.
As far as i understand, it's not possible with the Limited-Edition to create one single setup for both environments - not really convinient, but OK for my needs.

So i have created an InstallShieldProject which runs on x64 environments as expected on my W10x64. But now i want to create a x86 Setup :
I have changed the Platform target for all Projects from Any CPU to x86 and also created a new Configuration at the Configuration Manager to target x86 explicit.
But the resulting MSI (Setup) doenst executes under an x86 environment: With the default "Platform not supported" message - on x64 everything works fine.

Whow do i create a Setup for an x68 environment with InstallShield LE 2015?

(The "Setup.exe"-Bootstrapper from IS-LE runs under x86, but not the containing MSI)

To create a 32-bit package, you merely have to remove all items that are being installed into 64-bit file or registry locations. See also my answer to this related but not quite duplicate question where I go into further detail.

Or my employer is willing to sell you a more powerful version of InstallShield that lets you specify a platform for your .msi file, but if this is your only reason to upgrade...
