Google has an MSI installer for Windows meant for installing Chrome for all users, versus just the user account that installs it. As best as I can tell though, this installs the Stable channel.
I would like to have the Dev channel installed for all users. This is mostly because I am comfortable, prefer, and only use the Dev channel, but I do have the guest account enabled on this machine so if someone has to use the machine, I want them to have access to Chrome and not fire up IE.
Even though some sites claim the MSI installer will work for the Dev channel, it does only seem to install Stable (currently 10.0.648.204).
So then, how can I install the Dev channel for all users?

New Info
Well, since the Google Pack is now discontinued, people will need a new way to deploy Chrome for all users on a system. Thankfully, Google Chrome's Alternate Installer allows you to do just that. In fact, if one pays careful attention to the URL parameters, all kinds of interesting options present themselves... One can download any of the Stable, Beta, or Dev channels for one user or all users, online or offline installers. For the OP, this link will download the online installer for the Dev Channel for all users.
Old Info
Another option for getting Chrome available for all users is to install it via the Google Pack -- it uses Google's Updater mechanism rather than the MSI. It may also be required for the following instructions to work, as I'm not sure that the MSI installs Google Updater.
That said, once you have Chrome installed for all users, follow the instructions in Comment #1 on Chromium Bug #33682:
After this is done, the next time Chrome updates, it will update to the selected channel.
Also of note: The bug is marked as WontFix. Google does not plan to allow for deploying the Beta or Dev channels by default.
