If you have tried what has already been suggested regarding compatibility options and noCD fix,
[EDIT: Link in my first post .... ] you are left with only the GOG download, if the game is important enough to you.
Wait for a sale and you can get it for $5- USD or less.
- I have a few games from 2004>2006 (Still Life was released in '05) that have a problem on Win10 which is also
an issue on earlier 64bit Windows.
This was always due to a copy protection (DRM) that was incompatible with 64bit Windows. In those games that I have that used
these notorious forms of DRM using a noCD has always worked, as this circumvents the CD check.
As if that was no enough of a problem MS has made DRM an even bigger problem by introducing DRM Blocking with Win10,
which makes it necessary to use a noCD fix with hundreds of disc based games that use SafeDisk DRM.
( Not a problem for me, as I've used noCD fixes forever because I always hated having to use the disc to run a game.)
The two games from this series that were released in 2002 and 2004 - Syberia 1&2 both use SafeDisk, so the disc based versions
of these two games also require a noCD to run on Win10.
