There is a known issue between 3DF Zephyr and Dell Backup and Recovery. This happens due to a known bug in Qt (the library we use to draw the UI inside Zephyr, such as panel and buttons) , namely QTBUG-41416 and has been acknowledged on the Dell community too.

This bug affects all software that uses Qt as interface library, so if you are having issues with other software, this fix might fix them too.

The easiest fix would be to uninstall Dell Backup and Recovery or try updating it to the latest version.

If you don’t want to uninstall the Dell Backup and Recovery tool, you can unregister the shell extensions that cause this problem. In order to do so, this can be done by running the following commands as administrator:

  • regsvr32 /u “C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBROverlayIconBackuped.dll”
  • regsvr32 /u “C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBROverlayIconNotBackuped.dll”
  • regsvr32 /u “C:\Program Files (x86)\Dell Backup and Recovery\Components\Shell\DBRShellExtension.dll”
