Hi I am having issues with my byond I can download it fine but when I go to start it up nothing comes up but it's running because when I go to uninstall it says that byond is currently running. (I have downloaded directx)
This happens to me sometimes, too.

BYOND seems to try and hide out in your system tray. Your system try is in the lower-right of your computer screen, next to the clock. If you don't see a small BYOND logo there, click the expand arrow to see the rest of the apps in your system try. BYOND should be there.

If it's not, you're experiencing a different problem.
Sorry I did not check this thread, it doesn't show up in the system tray,
