1. Go to: C:\Program Files\Common Files\microsoft shared\Web Server Extensions\14\TEMPLATE\FEATURES\Quest.SharePoint.Auditing.Monitor_FarmFeature\FarmFeatureElements
2. Modify the Elements.xml file to only contain:
<?xml version="1.0" encoding="utf-8"?>
3. Run IISRESET for SharePoint to pick up the change to the feature
Note: If in the future, an upgrade to Change Auditor occurs or the Change Auditor SharePoint solution is re-deployed, the workaround above would need to be implemented again.
Waiting fix in a future release of Change Auditor.
