Blueprint Administrator: "Error: Control does not support transparent background colors" and then quits

Blog Post created by toleary on Aug 9, 2013

When using the Blueprint Administrator application, it may produce an error dialog box stating "Error: Control does not support transparent background colors" and then quits. This only happens in Windows Vista, Windows 7, and Windows 2008 Server. How can I fix it?


This error occurs because some functions of the Blueprint Administrator for the versions specified below do not support the transparency function in the Microsoft Aqua interface.


Right-click PharosSystems.Blueprint.Administrator.exe (found in \Program Files (x86)\PharosSystems\Blueprint\Bin in a 64-bit operating system) and choose Properties. From there, click the Compatibility tab and then check the box next to "Disable visual themes." Click OK to set and then relaunch the Administrator application.

Affected Versions

This affects:

  • Blueprint Administrator 3.5.x
  • Blueprint Administrator 4.1.x
  • Blueprint Administrator 4.2.x
  • Blueprint Administrator 5.0.x

Please note that Blueprint Administrator 5.1 and higher have been modified to support Aqua transparency effects.
