One way I achieved something similar, albeit, a while ago is as follows:

Provide a button called Update on a common page (may be a common file, if you are using many) and when users click that, it opens a xls in a network location and copies the code from that file to the local file and closes the newly opened files.

That way, whenever I had an update, I would send an email asking them to update code locally.

It worked as I had few users and updates were fairly few in number. If you want an auto update, what prevents you from checking the version number during each and every opening of the file.
