Aims courseware is generally, for some reason, configured to
only run on Internet Explorer, which will only (easily!) run on
Windows computers.
Thus, you can, in theory, only do Aims courseware on a Windows
computer. However, I have successfully done Aims courseware on a
Linux computer with Firefox and Chrome, disguising itself as
Internet Explorer. There's only a couple of minor things that
didn't work.
So it can be done, it just needs some fiddling about.
