Hi! I have been seeing the error described above on Ubuntu Jaunty 64, and the following terminal output: Code: ~/Desktop$ wine msiexec /i SteamInstall.msi fixme:heap:HeapSetInformation (nil) 1 (nil) 0 fixme:advapi:RegisterEventSourceW ((null),L"Bonjour Service"): stub fixme:winsock:WS_setsockopt Unknown IPPROTO_IP optname 0x00000013 fixme:winsock:WSAIoctl SIO_GET_EXTENSION_FUNCTION_POINTER {f689d7c8-6f1f-436b-8a53-e54fe351c322}: stub fixme:winsock:WS_setsockopt Unknown level: 0x00000029 fixme:winsock:WS_setsockopt Unknown level: 0x00000029 fixme:winsock:WS_setsockopt Unknown level: 0x00000029 fixme:winsock:WS_setsockopt Unknown level: 0x00000029 fixme:winsock:WSAIoctl SIO_GET_EXTENSION_FUNCTION_POINTER {f689d7c8-6f1f-436b-8a53-e54fe351c322}: stub fixme:winsock:WSAIoctl -> SIO_ADDRESS_LIST_CHANGE request: stub fixme:iphlpapi:GetAdaptersAddresses no support for IPv6 addresses fixme:iphlpapi:GetAdaptersAddresses no support for IPv6 addresses fixme:advapi:LookupAccountNameW (null) L"charlie" (nil) 0x32f80c (nil) 0x32f810 0x32f804 - stub fixme:advapi:LookupAccountNameW (null) L"charlie" 0x14a018 0x32f80c 0x14a4e8 0x32f810 0x32f804 - stub fixme:winsock:WSAIoctl -> SIO_ADDRESS_LIST_CHANGE request: stub fixme:iphlpapi:GetAdaptersAddresses no support for IPv6 addresses fixme:iphlpapi:GetAdaptersAddresses no support for IPv6 addresses fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:msi:ControlEvent_SpawnWaitDialog Doing Nothing fixme:msi:ControlEvent_HandleControlEvent unhandled control event L"Reinstall" arg(L"ALL") fixme:msi:ACTION_HandleStandardAction unhandled standard action L"SetODBCFolders" fixme:msi:msi_unimplemented_action_stub RemoveRegistryValues -> 2 ignored L"RemoveRegistry" table values fixme:msi:msi_unimplemented_action_stub RemoveShortcuts -> 3 ignored L"Shortcut" table values fixme:msi:ITERATE_CreateShortcuts poorly handled shortcut format, advertised shortcut fixme:msi:ITERATE_CreateShortcuts poorly handled shortcut format, advertised shortcut fixme:msi:ITERATE_CreateShortcuts poorly handled shortcut format, advertised shortcut fixme:shell:DllCanUnloadNow stub fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.VC80.CRT" (8.0.50608.0) err:module:import_dll Library MSVCR80.dll (which is needed by L"C:\\windows\\Microsoft.NET\\Framework\\v2.0.50727\\fusion.dll") not found err:msi:ITERATE_Actions Execution halted, action L"InstallFinalize" returned 1627 err:msi:ITERATE_Actions Execution halted, action L"ExecuteAction" returned 1627 However, I'm loathe to delete my .wine folder, as I have several useful things installed there! Any other suggestions? Cheers Charlie
