Installing and playing NBA2K9 without official patch?

[LAXLAkes]

Can you maybe explain how to install NBA2K9 without installing the patch? Steam doesn't start the game if it's not updated and there's no NBA2K9.exe in the folder once I installed 2K9 without the patch. The Nba2k9.exe that works without steam doesn't work on my PC, either.

Thanks,
