Hi, We use Rhino for CAD and I check from time to time if it will install under Wine and today it installed fine, (1.1.43). However, running the app fails when trying to check our licence. Here's the output: $ wine /home/nick/.wine/dosdevices/c:/"Program Files"/"Rhinoceros 4.0"/System/Rhino4.exe fixme:reg:GetNativeSystemInfo (0x32f65c) using GetSystemInfo() fixme:win:EnumDisplayDevicesW ((null),0,0x32f8c0,0x00000000), stub! fixme:shdocvw:PersistStreamInit_Load (0x1a82f0)->(0x32ddd8) fixme:shdocvw:OleControl_FreezeEvents (0x1a82f0)->(1) fixme:shdocvw:OleControl_FreezeEvents (0x1a82f0)->(0) err:ole:marshal_object object doesn't expose interface {00000126-0000-0000-c000-000000000046}, failing with error 0x80004002 err:ole:ClientIdentity_QueryMultipleInterfaces IRemUnknown_RemQueryInterface failed with error 0x80004002 I get a polite dialogue box informing me of this event, click OK and the app closes. In the Rhino system directory there is a separate app, RmaLicenceValication.exe and when I run this separately, I get no output from terminal but a dialogue box which says: "Command line parameter missing. The first parameter must be the full path to a license key." This is an install from CD with a valid license and any help would be very welcome. Nick
