Thanks for the very detailed instructions. I did as described and checked in Services to see if Intuit FCS was running. It was and was set as Manual trigger.

Today, after an attempted update overnight, the service is turned off and is set as Disabled.

I reset the updates and downloaded again - some of them worked, others didn't. The FCS service is still disabled.

It sounds to me that something more programmatic is going on here. In addition, other workstations on the network are having this same issue.  How can I get this problem dealt with??
