Thanks for that information, John. I installed cabextract, but I'm still having trouble installing the .dll. ($) sh winetricks mfc42 Executing w_do_call mfc42 Executing load_mfc42 Executing cabextract -q /Users/---------/Library/Caches/winetricks/vcrun6/vcredist.exe -d /Users/---------/.wine/dosdevices/c:/windows/system32 -F mfc42*.dll dyld: unknown required load command 0x80000022 winetricks: line 256: 21553 Trace/BPT trap "$@" ------------------------------------------------------ Note: command 'cabextract -q /Users/---------/Library/Caches/winetricks/vcrun6/vcredist.exe -d /Users/---------/.wine/dosdevices/c:/windows/system32 -F mfc42*.dll' returned status 133. Aborting. ------------------------------------------------------ Is there anything I can do from this point on?
