Symptoms

I am upgrading to 6.5.9 BUT the actual upgrade poath requires me to first upgrade to 4.5.1420
I get the following error running setup (also have attached the log file - which shows I cancelled the setup after getting this error)
Thanks

Diagnoses

As I mentioned on the call, this is a known issue with 1420 update. It has to do with attempting to load an AD property that is not returned in collection of properties, resulting in the exception.

 

Resolution

Click Back (goes back to the screen before Service Account Configuration) , followed by Next, then you were able to proceed the upgrade.
