Time for the next surprise in the GOG.com's Holiday Celebrations. We're still working on adding Windows 7 compatibility to some of the games which have some issues with the newest operating system from big M. We're happy to let you know that Arcanum: Of Steamworks and Magick Obscura and Myst: Masterpiece Edition are now fully compatible with both 32 and 64-bit Windows 7. To get the latest, Windows 7 compatible versions of the games, you have to re-download and install them again.
