Things to consider before upgrading

• When the desktop app encounters issues using peripheral devices at security levels 2 or 3, we recommend using Desktop App version 4.45.00 or higher. More information can be found in KB15298.
• In order to start the ClickShare App on the Button automatically when plugging it in, version 1.24 of the ClickShare Windows Driver needs to be installed on the device. More information can be found in KB12204.
• ClickShare Desktop App v4.30.2 or higher is required when using a Button to connect when the App is installed.
• ClickShare Desktop App v4.17 or higher is required to allow over the air (Wi-Fi and ultrasound) detection of the Base Unit.
• To optimize Wireless Presentation performance, we highly recommend always using a free 5GHz Wi-Fi channel. Changes and settings could be applied via ClickShare Configurator.
• Supports for Wireless Client Mode. A direct connection between the Button and the Base Unit is advised to better support Wireless Conferencing.
• Upgrading past Version 02.21.01 will not allow you to roll back to older versions before 02.21.01.
