While attempting to record with Camtasia, you may receive the following error dialog box:

Failed to start recording temp folder uninitialized

If you receive this message, it is because the recorder is configured to save the recording in a temporary folder that does not exist.  To correct the problem, navigate to the tools menu option in the Camtasia Recorder and select Options.  Make sure the path for the Temporary folder: text input is valid.
