Technically, you can (but by default the packaged installers will refuse 
to do so).  What you cannot do is run 64-bit R on a 32-bit version of 
Windows: the OS will refuse to run the executables (and if it is old 
enough, not even recognize them).

The only reason for mentioning this is for the record.  People do drag 
up R-help postings from years past (someone recently sent me a response 
to one from the 1990s).

We do plan to allow both versions of R to be installed on 32-bit Windows 
in the future (with a warning).  You still will not be able to run them, 
but you will be able to make binary packages for both versions: also 
this could be useful for system-wide installations from a 32-bit server OS.

 > but you can install a 32-bit R on a 64-bit OS, and you can later 
install 64-bit R as well. That is, installing 32-bit R does not 
interfere with your option to later install a 64-bit R.
