I want to exec a file named xt.exe (http://triana.escet.urjc.es/apliweb/xt.exe) in ubuntu. Then, I use wine cmd and the result is: Z:\home\michel\Escritorio>xt.exe err:ole:CoGetClassObject class {3efb1800-c2a1-11cf-960c-0080c7c2ba87} not registered err:ole:CoGetClassObject class {3efb1800-c2a1-11cf-960c-0080c7c2ba87} not registered err:ole:create_server class {3efb1800-c2a1-11cf-960c-0080c7c2ba87} not registered err:ole:CoGetClassObject no class object {3efb1800-c2a1-11cf-960c-0080c7c2ba87} could be created for context 0x7 Unable to start the application. The Microsoft virtual machine cannot be found. Anyone has an idea?
