Does "Force Google Chrome to run in this sandbox" allow chrome to automatically update?

Hi D A, 

You will have to disable forced programs and update Chrome outside Sandboxie. Then, delete the contents of your Sandbox and continue using Chrome forced.

Have a look at the Updating Firefox and its Add -ons section (it applies to any browser) for details on how to go about this:

Contrary to the other message in here, I actually find Google Chrome updates automatically as long as it's not installed inside the sandbox. If it's installed outside, a Windows service will update it automagically.
