Symptoms

After you have successfully upgraded Dimdim Publisher plugin on your Windows machine, you may see a missing plugin alert for upgrading Dimdim Plugin again and again while trying to start a meeting.

Reason

The issue could be of the following reasons:

1.  Firefox is not responding properly or Firefox went to a hung state.

Solution:

Terminate the Firefox application and start Firefox in a clean way. You can terminate the application's running processes in a way, depending on your operating system:

Use the Task Manager:

* Windows Vista: "Ctrl+Shift+Esc" -> "Processes" (or right-click the Taskbar and select "Task Manager -> Processes")

* Windows XP: "Ctrl+Alt+Delete" -> "Processes" (or right-click the Taskbar and select "Task Manager -> Processes")

* Windows NT/2000: "Ctrl+Alt+Delete" -> "Task Manager -> Processes".

* Windows 95/98/ME: "Ctrl+Alt+Delete".

In the list of running processes, look for "firefox.exe", "thunderbird.exe", "mozilla.exe" or "seamonkey.exe" (whichever applies) and terminate, if found. Note that multiple instances may exist so you should carefully check through the processes list and end each one.

2. Clean the outdated Dimdim plugin files from the Firefox plugins folder and install the latest Dimdim plugin afresh.

Solution:

1. In the Firefox Location bar, enter about:plugins.
2. Check if the Dimdim plugin is detected. If you find Dimdim plugin files listed in the about:plugins as “Dimdim Web Meeting Publisher Firefox Plugin”, that means that the Firefox plug-in folder contains the older Dimdim plug-in files which should be removed.
3. Exit the Firefox application. This plugins folder is typically located in the following location %APPDATA%Mozilla\Firefox\Profiles\"yourprofilename"\extensions. The plugin name will be   DimdimPublisher@dimdim.com. Please delete this folder and restart Firefox
