If you are experiencing an error 740 message in Windows Vista or Windows 7 when trying to launch an application, it means the software needs to Run as Administrator. 

“Error(740): The requested operation requires elevation.”

1. Simply right-click on the application icon and select Run as Administrator. Most the time, this will solve the problem.

2. Turn of UAC (User Account Control)
Open up Control Panel, and type “UAC” (without quotes)  into the search box.
Click the link for “Turn User Account Control (UAC) on or off”.
On the next screen, uncheck the box “Use User Account Control (UAC)”, and click OK.
This process is for Windows Vista and it’s slightly easier in Windows 7.
