Add DLL to GAC for Microsoft Dynamics CRM SSIS packages

I recently developed a SSIS package for Microsoft Dynamics CRM and after deploying it on the production SQL server I got this Error:

 Data Flow Task:Error: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Xrm.Sdk, Version=,
 Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
 File name: 'Microsoft.Xrm.Sdk, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
 at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e)
 at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PreExecute()
 at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPreExecute(IDTSManagedComponentWrapper100 wrapper)

Since multiple CRM SDK  assemblies has been referenced in my SSIS project, the package execution failed with file not found error. In order to fix the issue,  those DLLs should be added to GAC in production server and here are the steps  to do it:

  1. My production environment is Windows server 2012, SQL server 2012, .net framework 4.0.
  2. In order to register DLLs I used Gacutil tool. The tool is part of Visual Studio tool set and in order to have it in production: Copy these two Gacutil files from dev environment
    • C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\gacutil.exe
    • C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\gacutil.exe.config
  3. Paste two files to “C:\Windows\Microsoft.NET\Framework\v4.0.30319” folder in production (.net 4.0):
  4. Run the command prompt as administrator and execute below command for each one of the CRM DLLs. for instance:
    • “C:\Windows\Microsoft.NET\Framework\v4.0.30319\gacutil.exe” /i “C:\Microsoft.Xrm.Sdk.dll”

now the package should run successfully on production server.
