    If you are prompted for an administrator password or for confirmation, type the password or provide confirmation. If you have restricted access to the Windows computer you're logged into, you may not be able to access the Windows registry. Ensure that you have administrative privileges on your computer.   

  2. In the Registry Editor window, navigate to the folder path below:

    Computer\HKEY_CURRENT_USER\Software\Adobe\Lightroom

        • Yes: If the language value already set to en, run Lightroom.exe as an administrator to resolve the crash issue. The default installation path is: C:\Program Files\Adobe\Adobe Lightroom Classic CC\Lightroom.exe. See Run an Adobe program as administrator.
