It's always best to update your operating system if possible. But here are our requirements:
Windows XP, Vista, 7* or later, Mac OS X 10.6 or later, or Linux: RHEL 5.6 or later, openSUSE 11.3 or later, or Ubuntu 10.04 or later.
Here is our system check. This test will tell you if you're ok or need some updating.
*Windows 7 is no longer being updated by Microsoft. It's best to update your operating system to the newest version if possible. If you are going to be using a Windows 7 device or expect other presenters will be, please switch your webinar's codec to VP8 within the edit section of your webinar.
