Install files depend on 32 or 64bit OS

Hello,

in my Application I need to install files of a folder depend on the 32/64bit System.
E.g. c:\Prgram Files\MyApplication\thisFolder
The content files of thisFolder are depend on the System (32/64 bit).
So that I need to detect the 32/64bit -System and copy the right files into the the folder. during installtion process.
The name of the folder "thisFolder" should have always the same name.

Is the a easy way to do this with Setup Factory 9?

Thanks in advance
