On some systems, attempting to install the EZ Scan Digital PC Application will result in an "Error 740" message.  This message indicates that the installer does not have the access required to install the application onto the computer.  This error is typically caused by the User Account Control (UAC) on Windows Vista and Windows 7.

To successfully install the PC Application, navigate to the Software folder on the CD-ROM or the folder where you downloaded the installer.  Right click on the installer and select the "Run as Administrator" option from the menu that appears. This should allow the installer to run and properly install the PC Application.
