Is it possible to have two separate installations of Chrome on one computer?

I recently have a job that wants me to do a fresh install of Chrome, but I don't want to lose all of my extensions and settings. So is it possible to install Chrome again so I have two separate installations working under the same email? (Keep in mind I don't want dev versions, portable versions, or previous versions. Both need to be the same stable updatable version of Chrome.)

Yes, Assuming you don't want to run a virtual machine to have a second instance, you can have two different chrome instances if you use a os sandboxing software. For example Sandboxie.

Here is an image of me running two chromes. I didn't demo logging out of one but you can easily do that.

And here is an image showing Chrome running as two processes.
