(at least as I read the OP).  And I was assuming he might be using the Windows installer for
Tomcat, not unzipping.  That will set the machine up with only the 64-bit wrappers and native
dll.

Wrong again. The Windows installer (at least recent versions anyway)
will install the correct native dlls (32-bit or 64-bit) based on the JVM
selected during installation.
