Vista - Trust Not Granted error in WPF web application.

Hi All,

I'm a new in WPF. I've started developing WPF web-applications as my
previous backgroud is ASP.NET

I've developed a simple web-application and tried to present it to my
boss published the application under IIS on a developer server. Both
server and boss' computer has WinFX Beta 2 Runtime Components
installed. But I encountered with the following problem: I am able to
run the application on my computer, but my boss has a "Trust Not
Granted" error all the time ((

Furthermore I have the "Trust Not Granted" error when try to open the
"Web Paint Factory" sample on the
"http://blogs.msdn.com/ianm/archive/2005/12/12/502695.aspx" page.
(direct link:

Although the "Clock" sample works properly (direct link:
http://www.mobiform.com/demos/avalon...lonclock.xbap).

I have been googling for hours but I can't find out how to resolve the
problem ((

Can somebody give me an advice?

Thank you in advance!

Eugene.
