Can both 32- and 64-bit R be installed on the same machine?

Obviously, only relevant if the machine is running a 64-bit version of Windows – simply select both when using the installer. You can also go back and add 64-bit components to a 32-bit install. For many Registry items, 32- and 64-bit programs have different views of the Registry, but clashes can occur. The most obvious problem is the file association, which will use the last installation for which this option is selected, and if that was for an installation of both, will use 32-bit R.
