Can 16 and 32 bit versions of VISA exist on the same computer?

[oevidneg]

We have an application that we need to utilize both 16 and 32 bit versions however we are having problems with the 16 bit version reporting (no) VXI instruments through viFindRsrc - even though Resman reported the existance of such cards. Any ideas? Thanks

Just to answer this old question in case anyone else comes looking for the same thing: no, the 16-bit libraries use a different mechanism for getting information from Resman and the kernel drivers than the 32-bit libraries, so the information needed for the old libraries will not be present when using the new Resman and kernel driver. Since you can only have one driver installed, if you are using the 32-bit driver and Resman, the 16-bit library will not find any devices.
