Will wc 4.66 work with Foxpro 9? I am thinking of upgrading VFP 6 to VFP 9 and am wondering will all my code work, and if so will it work faster?

Yes - it will definitely work with 4.66. However, I would highly recommend you update to 4.68 which is the last 4.x version prior to the 5.x release which includes a ton of fixes including some critical ones that were made fairly recently. It should be a really minor update and it's free for you (change your download link and password to the 468 version number).
