No. 64 bit binaries (libraries inclusive) only run in 64 bit. To use
them in 32 bit, you need to also have their 32 bit versions installed.

If you are calling IDL from the command line, with the only difference
being the -32 switch, then you are calling the same IDL installation.
The possibility I had in mind of calling different versions was
through shortcuts, which could have been defined to point to different
places.

Anyway, you can check that it is the same version if from the IDL
session you check the of the !version variable.

In the command line, with the -32 switch. If you are launching from a
menu, using the shortcut marked 32 bit.
