Here's what I propose. Rather than changing the standalone installers, make the following site changes:
1- When someone signs up for an account, add a "What now?" section offering a download link for Galaxy & illustrating how to use it. Also mention the offline installers, and the difference between them. Mention the free games that are automatically added to new accounts & suggest that the user try them out to see how things work. Send a "welcome" email to the new user with this info as well.
2- When someone makes a purchase, add a "What now?" section offering a download link for Galaxy & illustrating how to use it. Also mention the offline installers, and the difference between them.
3- When accessing the library on the website for the first time, introduce a pop-up reminder about Galaxy that needs to be dismissed before download links are offered.
4- Add to the Galaxy client a means to initiate game downloads via the browser (similar to how Steam can with steam:// links) and offer those links by default, requiring the user to specifically choose the offline installers (and make the site remember this choice so it doesn't get annoying).
5- When someone downloads "backup" installers through Galaxy, have the client check for the latest Galaxy client installer and if it isn't found, ask the user if they would like to download that as well.
If you really must make changes to the installers, add a simple pop-up to the installers explaining what Galaxy is and offering a link to the Galaxy download page, or just add an entry for it to the carousel. Only do this for newer installers & when installers are being updated for other reasons, though.

adamhm: Wouldn't something like this be a lot better as well as a lot less work to implement?
Everything that adds more steps is most probably not better for UX. :) Especially that after you make a purchase, you just click to go to account and download it.
Popup on website is also just no good. We could make 5 popups about various things then.
We have links to Galaxy protocol ( goggalaxy://installGame/<GAME_ID>,en also launchGame and openGameView) and they'll be used at some point on the website, but Galaxy detection in browsers is not trivial. One click could start game installation just after buying the game.
