My subaccounts are software companies - all of them sell software. They like using courses to centralize the install instructions and support materials for their products, but they can't put the setup.exe installers in the lesson resource download area because .exe file extensions are banned. I can appreciate that the original intent was probably to avoid malware concerns, but at the same time, understand that people can simply link to a dropbox or similar in the lesson itself, so banning the file extension doesn't actually reduce the risk any - it's the perception of security only rather than actually meaningfully securing anything. Please make it an option so that the agency or subaccount owner can enable .exe files or any file extension if they elect to do so, with whatever warnings you think are appropriate when they turn this on. That would keep everything the way it is for most users, but allow the agency or subaccount to enable additional extensions if they need them for their particular use case.
