Diagnoses

This is a bug with 4.7.

When applying the fix, should the error below occurs:

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, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

This is due to Windows blocking the assembly. After copying the .zip coldfix file to the K2 server, please right click > Properties if there is an 'Unblock' option, please do so before application of this fix.
 

Resolution

A coldfix was provided to resolve this issue. To request this fix, please log a K2 Support ticket.
