The following might also be helpful: which version of Windows? 32 or 64 bit? is python the 32 or 64 bit build? Or just copy the header line from the interactive interpreter. For me:

Python 3.3.0rc2 (v3.3.0rc2:88a0792e8ba3, Sep  9 2012, 10:13:38) [MSC v.1600 64 bit (AMD64)] on win32

(although the win32 part seems wrong as this is 64 bit windows and amd64 build would not run on 32 bit windows)

Another suggestion: get 3.3.0, install in /python33, and try that (you should be able to select an option to have it not be the default install). This should not affect your 3.2 installation, and it will install its own copy of tcl/tk. In fact, if you do not have 3.2.3, you should be able to install that without disturbing your installed libraries.
