here is the steps to reproduce, I have wine 1.3.8: Code: $ export WINEPREFIX=`readlink -f .`/wine $ export XDG_DATA_HOME="$WINEPREFIX"/env $ export WINEDLLOVERRIDES="mshtml=" $ export WINEARCH="win32" $ winetricks dcom98 in the log this part seems the most interesting: Code: Executing wine /home/paolo/.cache/winetricks/DCOM98.EXE err:virtual:NtMapViewOfSection map_file_into_view 0x80000000 1000000 000000000 failed err:heap:HEAP_CreateSystemHeap system heap base address 0x80000000 not available err:virtual:NtMapViewOfSection map_file_into_view 0x80000000 1000000 000000000 failed err:heap:HEAP_CreateSystemHeap system heap base address 0x80000000 not available err:module:map_image Could not map shared section .sdata err:module:import_dll Loading library ole32.dll (which is needed by L"C:\\users\\paolo\\Temp\\IXP000.TMP\\advpack.dll") failed (error c000007b). According to error.c source (http://source.winehq.org/source/dlls/ntdll/error.c?v=wine-1.3.8) c000007b should mean ERROR_BAD_EXE_FORMAT. What can I try? I am seriously cramped as a productivity app depends on it (autocad 2000)... Thanks.
