Error: ArcSDE Repository unsuccessfully completed with Windows User Account Control
Windows machines that have User Account Control (UAC) turned on while running ArcSDE Post Installation a second time return this error:
"The ArcSDE Repository was unsuccessfully completed. Would you like to view the status?"
This is a feature of Windows.
Installation requires that the user be an administrator, not just a member of the administrator group.
This affects Windows 7 and any other Windows platform that is built on Windows 7, such as Windows Server 2008.
Solution or Workaround
Run the ArcSDE Post Installation as an administrator as shown below.
