Currently there are no legal downloads for Myst 4: Revelation that I know of, and the game is scheduled to be re-released in August this year at GOG, in a form made to run more easily on modern computers.

.7z is a compressed file type from 7-zip.
If a .7z file doesn't open with 7-zip it may be corrupt.
.iso files are disc image files.

I suggest you wait for the legal version. At best what you downloaded will get you a cracked version of the original game from 2004 that was made to run on Windows 98/ME/2000/XP.

dear jenny100,i think to listen to you,but for me is a little hard to wait so long, canot do better so i think i will wait
thanks a million

Hopefully you'll only have to wait a couple of months for the updated version.

If you want to play Myst III, you can try running it using ResidualVM (similar to ScummVM). But there is nothing like that for Myst IV.
