Fixed: Thunder Update Window installing progress stays on 0%

Some of you may experience a hang when they try to update their Thunder extension to the latest version using our Thunder Update Window. We have disabled our Update Window and the new version is already online (v.1.2.7.1), but you have to update using Visual Studio Extensions and Updates window. Just close our Thunder Update window when your VS start and update Thunder from the Visual Studio menu "Tools" -> "Extensions and Updates". Click on "Updates" -> "Visual Studio Gallery" in the right pane. Then on the left locate "Telerik Sitefinity Thunder" extension and click on the update button. Once we find a workable workaround to that issue, we'll bring that handy update window back.

Here is a KB article about the issue:
