I was wrong. Re-entering the version 10 serial number merely resets the IP addresses that are allowed to access the Coldfusion Server. The serial number shown in the \ColdFusion10\cfsuion\lib\license.properties file is correct for ColdFusion 10 Standard, however there is no previous serial number shown,. (Since this was an installation of a full retail version of CF 10, not an upgrade, that may be normal?) I tried stopping the ColdFusion services, deleting the "previous_sn=" line and restarting, but I am still running in developer mode.
The drives on our old server are dying so we really need to bring this new server online. Can anyone help?
