Any account that needs to run or configure FoxWeb will need read and write access to its registry key.  You can either place the account in a different group with more rights, or you can change the security configuration in the FoxWeb registry key as necessary.  In order to change the security configuration open regedit, locate hkey_local_machine\software\Aegis Group\FoxWeb, right click and select permissions.  Add the user(s) in question to the list and select Full Access.
