We are using Nintex 2013 Workflow Standard on SP 2013 Enterprise. We have been getting loads of errors logged in our ULS for a missing dependency on the RTC.Client.Psom. Below is an example:
Load Workflow Assembly: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Rtc.Client.Psom.ApplicationCore, Version=18.104.22.168, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.
We do not use Lync or office live so I'm wondering if there is a dependency within the Nintex workflow code that would be looking for this? If there is a better place on this forum to post please tell.
