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.

Ok, I'm pretty sure I know there are multiple versions installed.
I'll have to check when I get back to that computer. If if it is a
library problem, should all 64 bit libraries be able to run in 32
bit? What would I need to do to make sure it loads in the same
version but in 32 bit from the command line?
Basically it works in 64 bit but when calling > idl -32 and running
it, it comes back with a long string of warnings like this when I
start interacting with the gui:
> Warning:
> Name: Text
> Class: XmTextField
> Character '\63' not supported in font. Discarded.
and ultimately trips up at the openr command because it has the
directory path, but not the file name that I selected.
While we are on the topic, I'm migrating to a Mac and I know how to
call 32 bit IDL there... but how do you do it for a PC?

If they are standard IDL widgets, they should work the same in 32 and
64 bits. Have you checked whether you are getting into the same IDL
version and installation in 32 and 64 bits? The !version and !path
variables should indicate that.
Also, which system are you using? It could be that some external
libraries IDL needs are only installed in 64 bits.

Ok, just to check. Should widgets be able to work in 32 bit and I'm
doing something wrong? I'm modifying a friend's program to do my
bidding and it was made to open a gui to select a single image or a
directory of images to process. The biggest problem is the file
selected isn't remembered after being selected unless I manually type
it into the gui. If not, I'll just have to modify it to read in the
images without the widgets.

As far as I know, it cannot be done. Not even with an IDL_IDLBridge.
The choice at startup determines which set of IDL binaries get used.
The 64 and 32 bit binaries are, effectively, two completely
independent applications, that only happen to use some common files
(source, help, and resource files, mostly). So there is no way to jump
from inside one to another.
If there is really no other way around it, you could put the data into
a save file, then, in a 32 bit session, restore the save file and then
call the 32 bit routines you need. It is not pretty, but it could be
done without getting out of the 64 bit session, by creating a small
batch file that does the restoring and whatever else is needed in 32
bit, then spawning an idl -32 to run that batch file.
