When testing AADS on "slow" system, either slow because it is old hardware, or slow because the VM does not get enough CPU cycles from the Host, we have encountered the problem as indicated by KB2545627. The Hotfix did work OK for us.

Please note : It can take several minutes before it reports "Installed". Be patient when installing this Hotfix and wait for it to finish. After the reboot, check that the hotfix is installed:
