After the update to Windows 10 Fall Creators (Version 1709), the TOOLS for UR software does not work correctly anymore. Opening the dspMixFx application or starting Cubase/Nuendo initializes a Windows Installer dialog stating 'Preparing to install'. The Windows Installer has to be closed using the Windows Task Manager ('end task').
- Uninstall TOOLS for UR and the Yamaha Steinberg USB Driver completely.
(Right-click on Windows logo at the bottom left > Apps and Features)
- Restart the computer.
- Install the latest Yamaha Steinberg USB Driver.
- Install the latest TOOLS for UR for your interface (UR44, UR242, UR28M, UR824).
The error message should not appear anymore and it should be possible to access 'dspMixFx' and load Cubase/Nuendo normally again.
