Used the following tutorial:
Using the Windows registry
Find or create the following key in the registry: 32-bit Windows: HKEY_LOCAL_MACHINE\Software\Google\Chrome\Extensions 64-bit Windows: HKEY_LOCAL_MACHINE\Software\Wow6432Node\Google\Chrome\Extensions
Create a new key (folder) under the Extensions key with the same name as the ID of your extension (for example, aaaaaaaaaabbbbbbbbbbcccccccccc).
In your extension key, create a property, "update_url", and set it to the value: "https://clients2.google.com/service/update2/crx" (this points to your extension's crx in the Chrome Web Store):
Launch the browser and go to chrome://extensions; you should see the extension listed.
This method does not work for me. Please help me find a solution.
