Cubase 10. 5 : The "edit in wavelab" feature

Cubase 10. 5 : The “edit in wavelab” feature, in version 9.5 de Cubase, has disappeared from version 10 and 10.5? I look and i disfind.

It’s well stated in Wavelab’s manual:
Editing Cubase/Nuendo Audio Events in WaveLab Pro
Open your Cubase/Nuendo project in Cubase/Nuendo.

In the Cubase/Nuendo Project window, select the audio event that you want to edit in WaveLab Pro.
You can also select only a part of the audio event with the Object Selection tool.

Select Audio > Edit in WaveLab.
In WaveLab Pro, edit the audio event.
When you have finished the editing, click Trigger Cubase/Nuendo Update on the command bar.
The changes to the audio event are applied to the Cubase/Nuendo project.

Try reinstalling WaveLab. WaveLab installer writes a file somewhere, and Cubase knows, with this file, that WaveLab is able to be called.

Thanks, I’ll try.
