It was reported in the Windows 7 games thread that this first game of the series would not work on Windows 7. I have the Last Half Of Darkness Trilogy disk that has all of the first 3 games on one DVD, and the version of Shadows Of The Servants that's on this disk ran perfectly on my new eCollegePC computer with 64 bit Windows 7 Ultimate with no tweaking required. I just got finished, all the way through with no problems. The version that's on the Trilogy disk appears to be the download version, so I can't vouch for the original boxed version.
I just got started with Beyond The Spirit's Eye, which also appears to be the download version, and it is also running perfectly so far, after playing for about a half hour. The Windows 7 Games thread did report this game as being OK.
