10.2.0.2 is definitely available for Win32 (locate patch 4547817 on MetaLink through simple search by patch number,) but you can skip it and patch right to 10.2.0.3 (patch 5337014) - Oracle patchsets are cumulative. Carefully follow the instructions accompanying the patchset to apply it. Then follow the instructions in the note 369269.1 and I'm sure that with a little bit of luck it will work.
