That really surprises me because I have not encountered a single 
instance where a 32-bit application would not work - and many of them 
are (I think) too old to have been built with 64-bit compatible DLLs.

One oddity I did encounter was with the Java RE - I had to install both 
the 64- and 32-bit versions to get some applications to run. And the 
64-bit control panel clobbers the 32-bit one.
