I scanned the files in the directory c:usersmyusernameAppDataLocalGoogleChromeUser DataDefaultExtensions and found the folder with the Notifier files. I took those files and copied them to DropBox. I did rename the folder from apflmjolhbonpkbkooiamcnenbmbjcbf to reader.
On my laptop in Chrome I clicked Wrench -> Settings -> Extensions. You then have to check the developer mode. This enables the Load unpacked extension button. Click that and browse to the reader directory and then to the 1.3.1.0 directory. Click ok and the Google Chrome Notifier will load.
If you use this then I hope this helps. Oh, and in case you can’t find the code on another computer click here [Download Reader]
