ptoneclk.exe - Entry Point Not Found

[LindsayE]

Lately, when I start Webex, I get this dialog box:

Does anyone know the cause?

I click OK and have no problem using Webex.

Perhaps something "broke" during a recent Webex - auto-update?
You may try to un-install (= remove) the application and re-install it.
By default no administative privileges are required for this, but this may depend on your organisation...

Since all Webex-content (your teams, chat etc.) is stored in the cloud at Cisco, all you may lose
is the settings of the local Client-Application (UI-Theme, Audio and Video-settings etc..)
You may want to check your Client-settings before re-installing Webex...

Thanks Fritz. Uninstall/re-Install cleared the issue.
