If you use Webex, and have installed the Webex PPT add-in (to convert presentations to be uploaded), you may find that some of your add-ins don't work.

Apparently the Webex installer is very clever and smart, but too clever and smart for some addins. It uninstalls all (or a lot) other add-ins, then reinstalls after it is installed. Most add-ins are okay with this, but many of the more robust ones cannot simply be removed and replaced, they access other files that this process breaks.

Webex does make upgrades to its software and I have been told by at least one add-in developer they are working on fixing things... but just last week it rendered a few add-ins broken on a new system I was building.

So no solution or work around, but now we all know.
