I was poking around my environment today, and happened to notice the backup/export setting process was not exporting the settings.  I checked the job, everything looked okay, ran manually and nothing.  Checked the VisualCron logs and found the following:
11/12/2012 3:35:29 PM	Err	Error when backuping files, err: Can not load 7-zip library or internal COM error! Message: Your 7-zip library does not support this archive type.
Two questions here, how can this be corrected? (hopefully without a complete removal and reinstall)
And, why did VisualCron not mark this task as a failure?
thanks
