I am sure at some point of time you may uninstall one of the downloaders such as Orbit:
Don't get me wrong, I am not saying its a bad downloader, but it just happen that I could not use it effectively in office.
Anyway, what I am going to described probably may affect some of you out there. What happened to me was that during the installation, my Google did not exist completely. I had manually close Chrome, but somehow one of the instance must still be running during the uninstallation. Anyway, the result is that Orbit is not cleanly uninstalled. Whenever I tried to download something, it would still redirect to Orbit (and worse, it doesn't work anymore)
So, let's see how to clean up this mess.
1. Before you start, make sure Orbit is no more around (uninstallation from Control Panel)
2. Close all instances of Chrome. (Use task manager to check that here is no more instances running too)
3. Now, let's find the file "nporbit.dll". You can use search or under these directories:
4. Delete the file.
5. Open up chrome and type "chrome://plugins/"
6. Find Orbit Downloader and disable it.
That's all you need to. Well to fully clean everything, you can always reinstall Orbit. Reboot and uninstall Orbit... But its just kinda of troublesome...
