N5.5 won't start ! and Freeze the system

Upgrading to Nuendo 5.5 on pc with vista on Asus laptop.

Lauching N5.5 works until : Lecteur Video (Video Player) and freeze all Vista System !!!

So from I must switch off the computer to restart it.

Try to uninstall and reinstall, nothing changes. N5.1 continue to works.

Any Idea ?

Does anyone has the same trouble ?

Hi Gr,

what type of GPU does your Asus laptop have? Please make sure that Vista, the GPU drivers and QuickTime are up-to-date on your machine.
Nuendo 5.5 copies the preferences from an existing Nuendo 5 installation, so this could be the issue in your case.
Please rename your Nuendo 5 and Nuendo 5.5 preferences folders (also any older Nuendo/Cubase folders you might find) and restart Nuendo 5.5.
Info on how to remove the preferences can be found here:

If the problem persists please get in touch with me via the Support Request Form and we can take a look at your system.

Best regards,

Thanks a lot.

Removing preferences solved it !

Have a nice day.
