Sorry for the misunderstanding:
I performed a check of the entire RadControls for WinForms Q2 2011 (2011.2.11.712) distribution and could not find a pfx file.
Such a file doesn't exist in the Live Demos solution, nor in the other folders of the distribution.
Is it possible that you have installed a third-party plugin to sign the assemblies, or something alike?
