Explanation: If you are using one of the following "debug" shortcuts to stop and restart the Foxhound engine, try running it again. The previous dbeng11.exe process may not have had enough time to release the foxhound1_debug.txt file before a new dbeng11.exe process tried to open that file:

All Programs - Foxhound1 - Tools - Start Foxhound via Firefox - debug

All Programs - Foxhound1 - Tools - Start Foxhound via IE - debug

Here's a sample of this error message:

C:\ProgramData\RisingRoad\Foxhound1>ECHO OFF

If the problem persists, Foxhound may already running as a service and the "debug" shortcut may not able to stop the Foxhound database before starting it again. Look for an earlier message "Unable to stop database server -- Request to start/stop database denied.":
