    On the same note, there’s an issue I think with validating bulk serial numbers. We purchased 9 CF9 Std licenses which all failed during the install process (as per this note) but also through an error in the log file saying the serial is already in use on the network. I was told when we got them you only get 1 license and it’s valid 9 times, however, it’ may be a confusing error message for some.

    Thank you so much! I have been banging my head against the perverbial wall trying to get this installed. I opened a ticket on the support portal and that is completely worthless. This saved me quite a few headaches and a ton of time.

    I have been trying to get CF9 install on CentOS for weeks. It installs find under its own web server but I cannot seem to get the Apache connector to work. Anyone have a link to a good article about how to install the connectors manually?
