I have installed komplete 10 and set the correct paths in plugin manager
All the vst instuments are visible in the plugin manager window. And it all seems fine.
However, I can not see them when I open the Add new instrument browser.
Just a thought, have you had a look in the plug in manager under devices? If you had set up one of your own lists there, when adding new instruments i always need to drag them into my list before it will show up.
