Common PC System Requirements
The requirements for the administrator PC and the Webex Meetings Desktop Application user PC are the same.
Client and Browser Requirements
-
JavaScript and cookies enabled
-
Java 6, Java 7, or Java 8 (for web browsers that support Java) enabled
-
Cisco Webex plug-ins enabled for Chrome and Firefox
-
Plug-ins enabled in Safari
-
Active X enabled and unblocked for Microsoft Internet Explorer (recommended)
-
Enable Protected Mode disabled for all zones, for Microsoft Internet Explorer 64-bit
Note |
Because of Google and Mozilla policy changes, some users must manually enable the Webex plug-in when using these browsers to join a Webex meeting or to play a Webex recording. For more information and instructions, visit https://support.webex.com/webex/meetings/en_US/chrome-firefox-join-faq.htm. If a client is using a browser other than the specified versions of Chrome or Firefox and have Java enabled, the Cisco Webex Meetings application automatically downloads onto the client system the first time that client starts or joins a meeting. We recommend that you direct all clients to install the latest update for your Java version. |
TLS Requirements
Configure Internet settings on all user computers to use TLS encryption. For example, on a Windows PC select and Use TLS 1.2. We recommend selecting both options for maximum compatibility. (Use TLS 1.0 is not supported in versions 2.7 or higher.)
If your users host meetings for guests, such as people who do not work for your company, tell those meeting guests to manually update their operating systems and browsers that they must match the TLS setting before they join your meetings. If they do not modify their systems, they will experience compatibility issues. We recommend that you include these instructions in your meeting invitations. You can do this by editing the appropriate meeting invitations available on your Administration site at
