Okay, did "sh winetricks wmi" and installed, now got a new error where it just says: Code: Invalid parameter at System.Management.ManagementScope.Initialize() at System.Management.ManagementObjectSearcher.Initialize() at System.Management.ManagementObjectSearcher.Get() At Siemens_EMML.AppIsRegistered.DaysRemaning(Int32 ProductCode, String Registration, String Signature) And my terminal shows: http://pastebin.com/ib1qym5K It seems like it's almost done, just seems to not taking the registration properly. It's in the registry right, so not sure why it's failing out.
