We are aware of an issue with ConQuest 2.0 on some linux systems where it will fail to start if the system has not been registered. In the case of linux the error message detailed below will be given, in the case of MacOS a crash report will be generated.
ConQuest will start normally if registration has already been carried out, so in order to work around this issue we would recommend registering via one of the other CSD System components, such as Mogul or Mercury. As of ConQuest 2.0.1, the program will now instruct you to register via Mercury, rather than produce this error.
QCoreApplication::applicationDirPath: Please instantiate the QApplication object first
This application failed to start because it could not find or load the Qt platform plugin "xcb"
Reinstalling the application may fix this problem.
