Flash game isn't working in WebBrowser

In the beginning, I wasn't able to run a flash game on my webbrowser in visual basic. I then found out that there was a setting I needed to change and then flash started to work again for me.
I just sent the program to my friend and flash isn't working for him in his webbrowser. What do I do?

and the setting i changed was

Tools-->Options-->Show all settings-->checked
Projects and Solutions-->General-->Show advanced build configurations-->checked-->OK
Build-->Configuration Manager-->Active solution platform-->New-->x86-->OK-->Closed

What can I do to make it so that he is able to run flash from the webbrowser in vb? and our internet explorers work fine

We've also both ran everything as Admin.

 

Does your friend have the latest flash player activex?

Yes he does, it loads perfectly fine for him in IE

EDIT: He thought he had the lastest flash player. He didn't. and now it worked =P
Thank you
