single exe for 32 and 64bit

I have installed install shield 2008 premier version.
we are creating setup.exe for both 32 bit and 64 bit using install script MSI.

So far we are maintaining seperate project for them.

we require following information:

1) Is it possible to create single exe in Install script -MSI project type which will run in both 32 and 64bit operating system.
2) Whether this is supported in any higher version of install shield?
3) With install script project type this is achievable?

InstallScript MSI projects fall subject to Windows Installer's requirement of a separate package for each targeted platform. Note that a 32-bit package can be installed on a 64-bit system; it just cannot write to 64-bit specific locations. Pure InstallScript projects can support this, although it's not always the cleanest authoring experience.

Suite projects, introduced in InstallShield 2012, specifically target enabling you to include both a 32-bit package and a 64-bit MSI package in a single EXE file. The authoring is arguably more complex, as you need both MSI files and a Suite project, but the run-time installation experience is clean.
