Probably you will need to manualy install flash player.
Save the attached apk in your tablet (Downloads) using USB connection and follow the instructions down here:
In your tablet go to "Settings" > "Security" > "Unknown sources" and check "Allow installation of non Market apps"
Finally in "Settings" > "Storage" > "Downloads" find this apk click on it and "Install"
In any case use stock browser, remenber "Chrome" don't support Flash
I hope this help
