Cannot Load Project Files into the Configuration via Double-Click or Drag-and-Drop when UAC is Enabled
Last Update: 11/7/2018
Problem:
Because the Configuration has been launched with elevated privileges, it cannot receive window messages from a process that is running without the same privileges (such as Explorer). This occurs when UAC is enabled and a user that is part of the Administrators group launches the Configuration through the Administration menu.
Solution:
Launch the Configuration without elevated privileges. To do so, either double-click on the desktop icon or access the Configuration through the Start menu.
