The game installs fine on Windows 7 64bit (up to date) and it does run, except the quicktime videos don't play (any of them, from the intro, to age flybys, to Achenar and Sirrus' prison books). So for example, when you load the game it goes right to the Myst book sitting there, or when you ride up the elevator it just immediately jumps to the end. The latest version of Quicktime is installed and the videos work if I play them by going into the Myst folder. The transitions also seem to be stuck in zip mode, despite changing the settings.
There is at least one other person having similar issues (although he is reporting a crash as well, but I haven't gotten that far). http://www.gog.com/en/forum/myst_series/crashing_issue

Not sure if anyone else is experiencing this, but it looks like Myst may be one of the GoG games in need of a Win7 compatibility pass.

My videos aren't playing either... I switched to compatibility XP SP3 with admin privileges and all my crashing issues and low FPS issues went away. Then, in the very first book, I see some form of colour, but when I click on it, I don't get a video. Instead, it goes straight to the opening area.
Also, @flyingeagle855, if I remember correctly, the videos (the one at the beginning at least) is supposed to be poppy and crackly. Adds to the ambiance of the game. =3

Thanks krafty64 fixed my occurance of the same issue.

I'm running Windows 7. Game installs and launched, but when I select NEW game I get this error message:

Any thoughts?

Get checksum error on chunk 154 riven

I had a similar problem, but this solved it for me:

mystcommunity.com/board/index.php?/topic/33395-myst-games-in-vista-windows-7-incl-64-bit/

And i had to hunt down the Vista patch for Riven to nab it's Quicktime.qts file.
