A Dr. I support in my daily work is unable to enter an Adobe Connect meeting. She is using a Dell 760 computer.

When she types her name and presses enter, she is directed to a webpage stating she needs Adobe Flash Player 11.2 or greater. Adobe Flash Player 17 is installed on the computer. I have already installed Adobe Connect 9 Plugin for windows. Windows 7 in her operating system. What can I do to resolve her problem?
