Enterprise Vault 12.1 IIS Application fails
After upgrading Enterprise Vault to V12.1 from 11.0.1. the Enterprise Vault /EnterpriseVault application fails with
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.TypeLoadException: Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
This is hosted on a fully updated Windows 2012 R2 server.
All pre-req's are in place using pre-installation and checked with the deployment scanner.
This appears to be an IIS 8. error with .Net 3.5 and .Net 4 http activation protocols enabled.
Anyone have any ideas how to fix this for version 12.1 of EV?
There are some MS docs on this.
