"An error occurred while trying to make a connection to the datastore."
You can finish the setup, but afterward, you'll find that the service still won't start.
This is due to a glitch in the base OS itself. The fix is to execute these two commands (from the command line that you can get to via Start->Run->cmd.exe):
Code: Select all
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{A5CEB593-CCC3-486B-AB91-9C5C5ED4C9E1} /f
reg delete HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IASJet\Security /f
(This was covered in a support request with a customer because we initially thought that it was a corruption issue with our default install. It turned out that it wasn't, and I'm posting the solution here as a reference.)
