I run Windows XP Home Edition SP1 on a Pentium IV 2.53ghz 1gb ddr ram. I install the game from its original cd and download the Turbo Pascal patch and extract it to the game dir. I type "tppatch file0001.exe" in command.com and voila the game can start and run normal without the Runtime error. (Had the same problem with my Windows 98 Pentium II 233mhz 64/192(+added)mb sd ram.)
