I am try to use Oracle.DataAccess.Client namespace. I install Oracle Data Provider for .NET 188.8.131.52.00 on Server (W2003/.NET 2.0). But When I try to open connection I get error: Unable to load DLL 'OraOps9.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). I search for it and could not find an clue. What must I do?
