Solution:
You can download the games from here, then put them into the Program Files in the C drive, afetr that you can make shortcut from it and copy them into different places. However this is not an Windows Installation (NSI) therefore you can go onto the Control pannel and unistall it, you'll have to go to where you had the original game and delete it.
I will try to make installers by the next two or three months for all the most popular games on Bepary Games. The less popular ones will get the installer versions.
