Works just fine

Doesn't work on Windows XP SP2 at all (not even the demo of that game). It's a shame, because I still like this old game very much.

OS = Windows XP SP3. AMD 64 X2 CPU, NForce4 chipset. All drives NTFS.

The game installs fine, regardless of any installer compatibility settings. The game starts normally without any compatibility setting, but fails when attempting to start a mission (my error is a C++ error, but I've heard other see other errors).

Compatibility settings cause the game to fail because the use of any compatibility setting causes the copy-protection system to incorrectly conclude that the CD in use is not "authentic original." As usual, it's the "copy protection" that prevents the normal use of the software, in other words.

I have found no means around these problems.

I have it installed on an XP SP3 laptop as well and it works fine (even using "virtual CD" technology). This is a single-core machine, with the hard drive formatted NTFS as well. It's a single-core machine. No compatibility modes are in place. But it's older hardware, and all Intel.

So... the issue isn't XP SP3, and it isn't NTFS. It seems most likely to be associated with the multiprocessor core, or the AMD/nVidia hardware (versus the Intel hw in the laptop).

The demo mission of the star trek demo does work on the windowes xp but if i put the missions of the original game or play the original game without cd the missions doesn't work
