I was wanting to play around with the customizer but the option for the
customizer is not showing for me. I have tried 3 different versions:
2018.04.01, 2018.04.06 and 2018.10.13. I have uninstalled them and the
installed a different version. I have even manually gone through the
windows registry and deleted everything I could find about OpenSCAD before
installing a different version and nothing works.
