I play http://www.conquerclub.com in my free time. There is a Firefox/GreaseMonkey script for this game called BOB that also works on Chrome, but I can't get it installed on my new PC while it runs fine on my old PC.

When I try and click the Install button I get the message that extensions can only be installed from the Google Store. The script is not on the store.

How can I copy the extension to my new PC?
It isn't synchronized like the other scripts and I already tried to copy the folder to my C:\Users\user\AppData\Local\Google\Chrome\User Data\Default\Extensions folder without result. I hate to use Firefox just for this one extension. Has someone a solution?

This might work:

  1. Download the Chrome extension and open the .crx file with 7-Zip.

  2. Extract the contents of the archive to a directory somewhere.

  3. Open Chrome and type chrome://extensions/ into the address bar.

  4. Check the "Developer mode" checkbox.

  5. Click "Load unpacked extension" and browse to the directory where you extracted the files.

  6. The extension should now install.

  • I googled a lot before making this question, and i saw this solution, but there is no .ctx file just a folder with a manifest file and a .js script

  • @peter: Does the .js file by any chance end with .user.js? Nov 3, 2012 at 21:15
  • And importing it unpacked or trying to pack it doesn't work, manifest file niot found or incompattible..

  • @peter: Ah, then it is a UserScript and not a Chrome extension at all. You can install that by simply dragging the file on to the chrome://extensions page. Nov 3, 2012 at 21:18
