Try without a crack, with the original CD/DVD, too. Sometimes a not so perfect crack can cause weird problems, especially with a tricky copy protection which this game may or may not have.

Have you checked the Property window of the main executable? (I understand you've checked files but what files and how you didn't explain.) Also, isn't the version number displayed e.g. somewhere on the main menu screen?

All official patches are supposed to be either "intelligent" or display an error message when applied to the wrong region (US/EU/etc.), language, version. If you're worried, make a copy of the complete directory structure of ther installed game; after applying the page, you can recursively compare the files so see which have changed.

There's this patch: Myst 4: Revelation patch 1.03 (international). I tried to unpack it manually but it's not standard.
