I FOUND THE SOLUTION TO THE MEDIA PLUGIN ERROR:
I changed "User Account Control Settings" in Windows 7 to "Never Notify" about changes made to my computer.
After I changed this setting to Never Notify, I could then enter into viewer 2 witthout getting the media plugin webkit error. I could open and use search perfectly and view profiles
There is a JIRA on this and a lot of people trying to figure out why they are getting this error message, so something to seriously look into.
The way I found it was when i was in the phoenix viewer, the user account control would pop up and ask me if this program had permission every time i opened search or a profile.... so annoyed with that, I turned the user account control settings down,.. this didn't help so i turned them off. ... and... ummmm that fixed it and also v2 media pluging webit error message never appeared again )) ..
Hope this helps..... Kimber Carter.
