dNotes Client is free to use
32bit vs 64bit
In September 2018, Microsoft changed the default installation of Office 365 and Office 2019 to 64bit. If you install dNotes Add-in 32bit version and the add-in does not load, you most likely need the 64bit version.
To check, in File|Options|Add-ins|Manage Com Add-ins, select dNotes and check the Load Behaviour. If it reads: 'Not loaded. A runtime error occurred during the loading of the COM Add-in.' then the Add-in version does not match the PowerPoint version. You can confirm your PowerPoint version by clicking on File|Account|About, the top line will read: 'Microsoft PowerPoint xxxx 32-bit' or 'Microsoft PowerPoint xxxx 64-bit'.
dNotes Add-in is free to trial for 30 days.
It requires Microsoft Visual Studio Tools for Office and perhaps some .NET components which will automatically download on installation. A working Internet connection is generally required for the installation to succeed.
Installing from within your browser (Firefox/Chrome) can give an error. Unzip the file first and run setup.exe. If you unzip to the Downloads folder, the setup files will be marked as "downloaded from the internet" and a generic warning will always show. These applications are digitally signed and deployed using Microsoft ClickOnce technology.
