64 and 32 bits clients installed at the same time?

Does anyone know if it is possible to install both the 64 and 32 bit clients for 11g running on Windows Vista? I have a 64 bit server set up, but my non-Oracle application throws an error when trying to use the 64 bit client. I was thinking if I installed the 32 bit client (all the software is on one machine) as well, I could use that and get around the limitation of my application. Has anyone else done this? Any thoughts on if it would work, or if I would encounter trouble?

Thanks

There is no limitation about the number of Oracle clients you can install in a workstation.

Just install each one in a separate Oracle home and point to the right one, Oracle even provides a Home selector under Oracle installation products.
