Problem running examples

[Synergy]

I have downloaded and installed the SDK. I am having problems running the .NET examples. When I run I get this error message:

System.InvalidOperationException occurred
HResult=0x80131509
Message=An error occurred creating the form. See Exception.InnerException for details. The error is: Could not load file or assembly 'Interop.PDFXCviewAxLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
Source=<Cannot evaluate the exception source>
StackTrace:

Inner Exception 1:

Hello Synergy,

Have you read and ensured that you've installed the AX control correctly?
