Has anyone found a solution to this error when launching the Scanning module for the Web Client? We've got version 11 update 7 of the web client. When I choose either Basic or Standard, the machine gives this "Invalid connection" error, followed by message box with "object reference not set to an instance of an object".
We've removed and re-installed scanning, web tools, Office integration and the MS Visual C++ redistributables (both 2012 and 2015-2019).
