It seems our News update about the Cyan Pack on Steam was a little outdated 
On September 1st, Cyan Worlds has published a new version of Riven on Steam that fixes its incompatibility with Windows XP, all you need to do to make it work is enabling the Windows Compatiblity Mode for Riven.exe and select "Windows 98" mode.
There are still some known issues, all solvable with a bit a patience, just follow the link below.
