Unable to repair or uninstall Ablebits add-in

If you try to install a new Ablebits add-in for Excel when an older version of the product is already installed on your machine, you may face a problem with Windows Installer Package. In the majority of cases, this may happen because the .msi file was lost or the add-in file was deleted or renamed. First of all, try to uninstall an old add-in version via Control Panel instead of Apps & features in Windows 10. If for any reason it doesn't help and you still receive an error message, please follow the troubleshooting instructions on this page.

• Uninstall via Control Panel
• Remove AblebitsLoader.exe before uninstall
• Delete registry data
