We have installed a Impressions 2.1 DVD. And whenever we launch it it gives this error message "You dont have the necesary hardware installed".
1.50GHz(400MHzBus),P4,Dell Precision 330,MiniTower,
Pinnacle DC1000 card,
nVIDIA GeForce 2 GTS,32MB DDR Video Card,
3 36GB,SCSI,U160/M,10K RPM,Hard Drive,
DVD+RW and CD-ROM,
among other things on that machine.
Looks like you have everything necessary plus more, the only thing I could think of that might be the problem is that it might be looking for the newest version of direct X (version 8.1, I think). Hope this helps.
