After install parallels toolbox (16.0.0) running an app with registered protocol doesn't work

Hi,
I have problems running and app with registered protocol
This in parallels 15, with parallels toolbox reinstalled is working, when I install parallels 16.0 is also working, but when I install parallels toolbox (16.0) it doesnt works.
What it can be?
Thanks

 

Hello, we doesn't have Parallels Toolbox 16.0 version.. Did you mean Parallels Desktop?

 

Exactly, Parallels Toolbox with Parallels Desktop 16

 

Could you please provide us with your Parallels Toolbox version?
And please share with us detailed issue description.
Looking forward to your reply.

 

I will try to explain me better:
I use an application that can works with URI protocol, like, for example, slack (slack://). More info: this: https://en.wikipedia.org/wiki/List_of_URI_schemes
In parallels 15 is working, you can run "slack://" and the app launches, but in parallels 16 (after install parallel toolbox) no, it says "Application not found"

 

Okey, I have more info.
I use Windows 10 with all windows updates in Parallels 16
If I uninstall Parallel Toolbox, all protocols are working, like: slack:// or spotify://
But with Parallells Toolbox installed

 

But with Parallells Toolbox installed, is not working*
