Hi Nicholas Hebb from BreezeTree here.
If the FlowBreeze ribbon tab does not load, I recommend that you uninstall it, go to the downloads page on the breezetree.com website, and then download and install the Admin version. Historically, this has resolved the vast majority of reported loading issues.
The difference: The default setup file installs the add-in to your AppData folder, which is Microsoft’s recommendation, and runs only for the user profile that ran the setup. The Admin setup installs to the Program Files directory, and runs for all user profiles on the system. As the name implies, running the admin setup requires admin privileges on the system.
To be honest, I am not totally sure why the admin version resolves the loading issue, but I suspect that it has something to do with the security settings on the system blocking add-ins loading from AppData – whether that be IT policy or antivirus software settings.
