Ages ago I installed a shareware product. And it also had a scrollable "terms and condition" screen (about 2 pages long) when starting it for the first time. When you clicked the "I Agree" button too quickly it would ask you "Do you really agree to the terms you read in only 0.76 seconds?" |

The installer presents the end-user license agreement (EULA). Immediately following it, it presents a multiple-choice quiz that asks questions about core parts of the EULA, such as permissible use, cancellation, refunds, jurisdiction/arbitration.
The installer then contains all the files to be installed. They are encrypted with a key that is composed of a hash value of the correct answers to the above quiz.
In this way, you could tie together whether someone reads the EULA with the possibility of performing the installation at all. This, in turn, causes successful installation to act as implicit proof of having read the terms. The order of the values must be randomized to prevent transmission of correct answers by index number only.
