Solution

Note: Prior to editing the EVStorageQueueBroker.exe.config file, it is required to make a copy of this file for backup purposes.

1. Stop the Enterprise Vault (EV) Storage Service.
2. Browse to the EV Installation folder (Default = C:\Program Files (x86)\Enterprise Vault\)
3. Locate the EVStorageQueueBroker.exe.config file. Copy this file elsewhere for backup.
4. Edit the EVStorageQueueBroker.exe.config to verify the <runtime> section is correct:
   • Example of incorrect value:
   • <codeBase version="10.0.4.0" href="x64/PerformanceCountersRCW.dll"/>​
   •  
   • Example of Correct value (EV 11.0.1):
   • <runtime>
   • <generatePublisherEvidence enabled="false"/>
   •     <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
   •       <dependentAssembly>
   •         <assemblyIdentity name="PerformanceCountersRCW" publicKeyToken="26c5e2ccf2b9267c" culture="neutral"/>
   •         <codeBase version="11.0.1.0" href="x64/PerformanceCountersRCW.dll"/>

   •     </assemblyBinding>
   •   </runtime>​
5. Start the EV Storage Service for the changes to take effect
