How a typical user installs a program: Next, Next, I agree, I accept, OK, Yes, Finish. Lots of people do this, even when the setup program is translated into their native language. So, here are some suggestions to prevent users from accidently accepting the agreeing the sponsor agreement and then posting everywhere "Stay away from Messenger Plus! It is now bundled with adware!"
User must click that big button with red text on it to continue to the next page. The big button cannot be clicked until the 10-second countdown is over. (notice the :00)
(I did not modify this screen)
The "big" version of the sponsor agreement,
with the toolbar screenshot, but no I accept / I do not accept thing yet.
User must scroll down to the bottom before the Close button can be pressed.
(In the current version, to see the "big" version of the sponsor agreement, you click the little + sign at the top right corner of the sponsor agreement)
A short message for people that did not actaully read the agreement.
A final screen where the user can verify the choices he/she made, including the installation of the sponsor program.
