2016-05-25 09:15:58,086 ERROR [ 7] [(null)] Failed to initialize InProcServer. ServerType='Omni.Riva.Sdk.GroupWise.GwSdkConnection' Endpoint='net.pipe://localhost/RivaSyncService/InProc/3760/GwSdkService.svc'
System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Program Files (x86)\Omni\Riva\Application\Base\Omni.Riva.Sdk.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///C:\Program Files (x86)\Omni\Riva\Application\Base\Omni.Riva.Sdk.dll' ---> 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 for more information.


The file used to install Riva On-Premise was blocked by Windows. That means that all files extracted from that zip file were also blocked.

Note: The issue reported in this article is not specific to the file or the GWSDK dll files. The Blocked security could happen to any ZIP file downloaded from the internet, and the ZIP file should be checked before extracting the files.


To reinstall Riva with an unblocked .zip file:

  1. Remove the Riva files and folders previously extracted from the blocked file.

  2. Right-click the file, and select Properties.

  3. Select Unblock, and select OK.

  4. Follow the normal procedures to extract the files from the zip file and continue setting up Riva.
