3. In the right pane of CurrentVersion registry key, look for the ProgramFilesDir named registry string (REG_SZ) and make sure that its Data points to C:\Program Files, where C: is the drive on which Windows is currently installed. If you’ve installed Windows to different drive, remember to substitute it here.

Once you done this registry manipulation, close the Registry Editor.

You can retry working with Windows 10 setup and this time you should be able to go ahead and install Windows 10.
