I want to know if there is a fix for Myst IV on windows because I have a problem that whenever I try to launch the game on windows 10 it will not even open.
That is probably because of the DRM.
Google for a patch or NoCD for your version of the game.
At one point Ubisoft themselves had a "patch" that removed the SafeDisc DRM, but Ubisoft rearranged their website so the old link won't work anymore. It used to be located athttp://help.support.ubi.com/mystIV_v12_ncd.zip
but the link hasn't worked for years.
This patch may not work with later versions of the game anyway.
There are NoCD's for different versions though.
Even if you get rid of the SafeDisc DRM, there might be some other conflict with Windows 10. But the DRM on Myst IV makes even trying to get it to work a non-starter unless you have a NoCD.
