NVDA Reads "Unknown" within Respondus LockDown Browser
Posted by Respondus Support
If NVDA only audibly reads "Unknown" within Respondus LockDown Browser, it is due to the portable version of NVDA being used.
Only the full Desktop version of NVDA should be installed and used with LockDown Browser.

To resolve the issue students should do the following:

1) Remove the portable version of NVDA

* Find the location of the folder the NVDA program was installed in
* Select all the files of the NVDA program, right-click, and select "Delete"

2) Install the Full Desktop version of NVDA

* Download the installer from here: https://www.nvaccess.org/download/
* Double-click the installer once it has downloaded
* Be sure to select the "Install NVDA on this computer" button and *not* the "Create portable copy" button

* Open NVDA if it is not already running and launch LockDown Browser to see if the problem is resolved
