Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.EnterpriseManagement.DataAccessLayer, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.File name: 'Microsoft.EnterpriseManagement.DataAccessLayer, Version=7.0.5000.0,Culture=neutral, PublicKeyToken=31bf3856ad364e35' at GatewayInsertionTool.Program.Main(String[] args) WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].



The file ‘Microsoft.EnterpriseManagement.DataAccessLayer.dll is not where the …Gatewayapplovaltool.exe ist.

Copy the two files from the source folder supporttool  to the SCOM installation subfolder named “Server” .




  • C:\Program Files\System Center 2012\Operations Manager\Server

Now run the command out of the server folder.
