Hi Wine friends Finally I could fix the ""err:rpc:I_RpcGetBuffer no binding"" modifying the Wine's default Windows version to W7 on winecfg. But now here is a new error msg: Unhandled Exception: System.NotImplementedException: The requested feature is not implemented. at System.Security.Principal.WindowsIdentity.get_Groups () [0x00000] in <filename unknown>:0 at Oticon.InternetUpdater.Common.Config.get_LocalizedUserGroupEveryone () [0x00000] in <filename unknown>:0 at Oticon.InternetUpdater.DownloadService.RemotingProvider..ctor (IBitsManager newDownloadManager) [0x00000] in <filename unknown>:0 at Oticon.InternetUpdater.DownloadService.UpdaterHostService..ctor () [0x00000] in <filename unknown>:0 at (wrapper remoting-invoke-with-check) Oticon.InternetUpdater.DownloadService.UpdaterHostService:.ctor () at Oticon.InternetUpdater.DownloadService.Program.Main () [0x00000] in <filename unknown>:0 Right now the situation is: I have installed the mono26 from winetricks because the msg: ""install the Windows version of Mono to run .NET executables"" and the msxml6 from winetricks because the msg: ""Failed to load DLL C:\windows\system32\msxml6.dll"" By the way I am installing in Ubuntu 10.04 Do someone knows how to handle this Unhandled Exception? Thanks an regards Lorue
