We have been having an issue where we cannot start SMACC, we click on the SMACC icon, and nothing happens. We have tried running as administrator etc. But we have not been able to start the application.
Looking at the SMACC log (Located at %APPDATA%\SnowSoftware\Logs\SnowMACC.log) we see the error message:
2017-08-29 15:42:36 DEBUG SnowSoftware.Program:Main - SnowMACC starting..
2017-08-29 15:42:36 ERROR SnowSoftware.Program:Main - System.IO.FileLoadException: Could not load file or assembly 'LicenseManager.Plugin, Version=8.0.6407.21626, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'LicenseManager.Plugin, Version=8.0.6407.21626, Culture=neutral, PublicKeyToken=null' ---> System.NotSupportedException: 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.

The only change we have made recently is applying an update using the Snow Update Service, but not sure if that is related.
