thanks for the py2exe how-to! i think as step 7 you should bind your acknex.dll to the distributable exe.
...
can 64bit python use extensions that use 32bit libraries (since acknex.dll is 32bit)?
thats the main problem i think,cause when i tried to run the code it's said "not valid win32 application" :(,i thought that we can make sort of performance 'hack' by mixing python64+legacy(acknex32) but yeah failed
