 | Update for Microsoft Enterprise Single Sign-On v4 (KB2252691) |
This update corrects an assembly registration that causes a failure when .NET 4 is present on the system
- This update fixes an issue that prevents the ENTSSO service from starting, after installing .NET Framework 4. The registration of an assembly used by the Enterprise Single Sign-On Service to access SQL Server does not specify the correct version of the .NET Framework. When .NET Framework 4 is installed, the assembly will try to use the newer framework and then fail to load.
