Silent install using exes

Hi all,
We have created exes and msi file to perform the silent install of Installation Manager and RTC 3.0.1.2 eclipse client. As we have more than 2000 jazzusers , we are trying to push the installation via GPO (Group Policy Object). As we have a combination of 32-bit and 64-bit OS users , What is the best possible way to do this ? For instance if we we try to push the install of 32-bit in a 64 bit OS it will throw an error. Is it possible to do the installation after finding the operating system architecture and then push the installation?
Thanks,
Adhithya
