I am getting this on my screen on my new Dell Windows 11 computer. Any idea what to do? ![image](https://europe1.discourse-cdn.com/steinberg/original/4X/d/c/c/dccc19816a91bb609338ca519c48a198e4a0b8c2.png) ---

Are U using something with Dante? Program Compatibility Assistant is a new “feature” on Windows. It introduces more problems than it solves. ---

Bonjour is an Apple discovery protocol, often installed by iTunes. If you type “bonjour\mdnsNSP.dll” into a search engine you will find some suggestions. Mine was eventually solved by installing an old Apple printer driver, I think because an iLok required Bonjour. Don’t worry, it’s only annoying, not harmful. ---

Bonjour is also the Dante device discovery tool used by Dante drivers. Since the Apollo 16D it is part of the UA driver bundle. ---

I wonder how many other products are using it? It looks like the real solution is for Bonjour to be fixed so it passes the security checks so that we don’t have to use an old version as a workaround. ---

There are some reasons… First, it is intended to search the network. So it needs network access. MS new feature detects network access and warns the user. MS needs to fix its behavior. ---

Cubase 15 uses Bonjour to connect with Cubase iC Pro (the iOS Cubase remote utility). The accepted answer references “installing an old Apple printer driver” - Steinberg’s support for Cubase iCloud Pro has a link to the Bonjour for Windows download which is a Bonjour Print Services utility. See this link for the Steinberg support page and scroll down for the link to the Bonjour for Windows installer on Apple’s website. > **[Cubase iC Pro: system requirements, installation and setup in Cubase](https://helpcenter.steinberg.de/hc/en-us/articles/12980237699218-Cubase-iC-Pro-system-requirements-installation-and-setup-in-Cubase)** > > Cubase iC Pro is an app for iOS, iPadOS, and Android that lets you control Cubase from a smartphone or tablet via Wi-Fi. In this article, you will learn everything about installing Cubase iC Pro an... ---
