17 Jul 2014 4:51 PM Recently I came across the following error...: "A CLR error occurred while invoking the scheduling engine". To address this issue, do the following: Go to Start and find the Admin tools. 2. Locate the Server configuration service 3. Double-click on it. 4. Make sure this parameter is NOT checked. That should may take care of it. Note: I have seen other cases for this a error as well.
