[My answer assumes you're trying to use Chrome as a replacement for the TBB, to the same anonymous ends.]
To cut a long story short: don't use Chrome.
Even if you get it "working", your privacy won't be as protected as it is when using the Tor Browser Bundle and the modified version of Firefox contained therein.
For more details on why not to use Chrome, see the Tor FAQ (which itself links to and article on the Tor Blog describing the problems with Chrome).
For more information about the changes that have gone into Firefox - and therefore what isn't present in Chrome - this thread would be a good place to start: What are the changes made to Firefox in the TBB?
