Sorry for the delay in responding on this.  Answers to your previous questions below.

•  How do you remove QBFC? This is the QBFCMonitorService correct? do you remove it via registry or just do a 22 or 23 repair?  sc delete command (sc delete QBCFMonitorService).  With 64bit and 32bit installed side by side, QBFC can run as either architecture.  if you happen to go look at the path to executable on the service itself, it will be pointing to Program Files (x86) on machines not working with 32bit and 64bit installed side by side.  Once the service is gone, you can run the program repair (in add/remove programs) with 64bit version of QB.  That will reinstall the QBFC service but will now be utilizing the 64bit version of the service.  Can verify by looking at the same Path to executable property on the service after the changes.

•  Which option did you run in ToolHub quick fix or diag tools? Both do not seem to work however.
  Won't hurt to run both, but the 'Quickbooks Program Diagnostic Tool' should suffice.
  
  Hope this helps you get it resolved!
