Q6600010: When I start the Manager, I get Error '25004 "Unable to open Configuration Database".

When you start the Manager and get Error 25004: "Unable to open Configuration Database", there's most probably a security issue where the ActiveXperts Network Monitor Manager cannot read the Configuration Database (CONFIG.SDF). The application will close immediately.

The easiest way to find this out, is by launching the Manager using the 'Run As Administrator' option. One way to do this is, is by pressing the SHIFT key and hold while you right-click the Manager shortcut item in Windows Start menu. Then, choose 'Run As Administrator'.

Once confirmed that it is a security issue, check out your NTFS permissions on the ActiveXperts installation directory (default: 'C:\ProgramData\ActiveXperts\Network Monitor').
