Logos won't open after instillation/update

Nick Whitney

Attempt to start Logos after instillation/ update and it says "A problem caused the program to stop working correctly. Windows will now close the program and notify you when a solution is available".  This problem has been persistent for some time. Have attempted to reload Logos 4 different times to correct the issue with no success.  Logos Log files in zip folder attached 8880.Logos Log Files.zip

The error in the logs is:

Could not load type 'System.ServiceModel.FaultContractAttribute' from assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

This looks to be a problem with the installation of the .NET Framework itself. Try following the instructions in this answer to repair the .NET Framework: http://superuser.com/questions/729839/how-to-repair-net-framework-4-installation-on-windows-8
