Empty gray meeting window when using the desktop app

When you start or join a meeting, the meeting window is launched, but the window is empty (gray) and you cannot enter the meeting room. This means the meeting room uses our earlier Flash-based technology. Flash-based meeting rooms are not supported on desktop versions 6.18.4 and newer.


  • If this is your meeting room, we recommend downloading the 6.17.1 version of the Mac or Windows desktop app to launch your Flash-based meeting room.
  • If you are attending the meeting, we recommend you join the meeting using a web browser that supports Flash. See Enable Flash.
