Hi Eric, Could you be more precise ? I have I installed fmincon on at least 10 different machines for testing purposes (mostly under Windows 10) and did not encounter any problem. Atoms is, I must say, a very unstable (not to say crappy) piece of software and in particular very hard to use smoothly when your are developing some modules and play e.g. with offline mode.
What I would do first is to uninstall every module then install fmincon. If problem is still here please help me by debugging a bit...
