NotSupportedException at :
An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information. (HRESULT: 80131515)

While it is possible to "unblock" every assembly file individually, you may want to unblock the entire downloaded SDK zip archive. To do so, right-click on the original SDK archive and select 'Properties' to view attributes. At the bottom of the General tab, verify if Windows displays a warning message about blocking the file. If you have such a message, click on the "Unblock" option and re-extract the archive. After you have added a Spotfire distribution to the Package builder, validate the distribution.
