C:\ProgramData\RisingRoad\Foxhound4>ECHO OFF Start Foxhound Engine SQL Anywhere Start Server In Background Utility Version 16.0.0.2127 DBSPAWN ERROR: -81 Invalid database server command line ****************************************************************** *** ERROR ******************************************************** *** dbspawn/dbsrv set ERRORLEVEL = 1 05/15 11:00:33.

If you're trying to run Foxhound 4 on Windows 10, you may have to use "Run as Administrator" to launch the Foxhound batch files.

Here's how you can set "Run as Administrator" for the Foxhound shortcuts in Windows 10:

All apps - Foxhound4 Right mouse on Start Foxhound Engine Click More - Open File Location See this folder appear: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Foxhound4\Tools Right mouse - Properties on Start Foxhound Engine Select the Shortcut tab. Click Advanced. Check Run as Administrator. Click Apply.

This message may also mean the Foxhound database was already running when you tried to start it again; for example, you used the Foxhound4 - Tools - Start Foxhound Engine shortcut when the Foxhound database was already running.

If you want to restart the Foxhound database, try using the Foxhound4 - Tools - Stop Foxhound Engine shortcut first.

With some of the shortcuts, like Foxhound4 - Start Foxhound via Chrome, you can just ignore this message and press a key to contine opening Foxhound in the Chrome browser.

If you are using one of the following "debug" shortcuts to stop and restart the Foxhound engine, try running it again. The previous dbsrv16.exe process may not have had enough time to release the foxhound4_debug.txt file before a new dbsrv16.exe process tried to open that file:

All Programs - Foxhound4 - Tools - Start Foxhound via default browser - debug

All Programs - Foxhound4 - Tools - Start Foxhound via Chrome - debug

All Programs - Foxhound4 - Tools - Start Foxhound via Firefox - debug

All Programs - Foxhound4 - Tools - Start Foxhound via IE - debug

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."
