I am trying to convert a project from MX4 version 4.8.11 to Mx5. I have tried 5.1.1, 5.21.2, 5.21.5, 5.21.6 and 5.21.8 but in all cases the conversion wizard will not appear and I just get a popup error telling me the version of my project is not compatible with the Modeller.
Can anyone tell me what I am doing wrong please?
