I have a need to install and register both 32 bit and 64 bit versions of a dll when on a 64 bit system from a single MSI used forinstalls on 32 and 64 bit systems.

Can this be done via InstallShield ?
If yes what version?

It's not possible because of a limitation with Windows Installer. See the following post in Heath Stewart's blog for details:

What I did was to install the 64 bit Dll to the appropriate directory and invoke the 64 bit regsvr32 in a custom action.
