Bootstrapper.exe doesn't start on a non-English version of Lync Server 2013 RTM

Applies to: Lync Server 2013


Consider the following scenario:
  • You're on a Microsoft Lync Server 2013 RTM (5.0.8308.0) server that's running a non-English version.
  • You install the May 2015 Cumulative Update 5.0.8308.887 on the server.
  • You run the Bootstrapper.exe executable file.
In this scenario, Bootstrapper.exe can't be started. Additionally, you receive the following error message:
Error: The given key was not present in the dictionary.

└ Type: KeyNotFoundException

└ at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
at Microsoft.Rtc.Internal.Tools.Bootstrapper.BootstrapperTask.RemoveUnusedFeatures(Boolean scorch)
at Microsoft.Rtc.Management.Internal.Utilities.LogWriter.InvokeAndLog[T](Action`1 action, T arg)


This issue occurs because a change in the Microsoft.Rtc.Management.Deployment.dll file in the English version of the file hasn't been made available to the non-English version of the file.


To fix this issue, install the April 2016 cumulative update 5.0.8308.956 for the Lync Server 2013, Core Components.
