Entperises vault dll register task Is not running during upgrading from enterprise vault 10 to 11

During upgrade form version 10 to 11 at the first reboot enterprise vault runs the dll registration process but some time it failed to start registration , these behavior is especially identified in tightly hardened servers.

Error :-

An error occurred in the thread control of enterprise vualt .net server processes

Because of above mention scenario , lot of .net related error was reported in event logs and I was failed to start storage service too. However database upgrade was completed successfully as it required directory and indexing service to start

3) “C:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe” /tlb /codebase /verbose “C:\Program Files (x86)\Enterprise Vault\KVS.EnterpriseVault.ServerManager.dll”


Steps -2 :-  below option also doesn’t help full

  1. Run fileReRegister.bat from enterprise vault installation directory


Steps -3 :- final and permanent solution

  1. Stop enterprise vault service
