DirectXP

Evo imam neki problem s half-lifeom.
Kada hocu da ga instaliram tj. pokrenem setup.exe pojavi se greska na kojoj pise:

16 bit Windows Subsystem
C:WINDOWSSYSTEM32AUTOEXEC.NT. The
system fie is not suitable for running MS-DOS
and Microsoft Windows applications. Chose "Close" to terminite application.

Eto to piše.Ima li iko ideju sta moze biti.Nece na Windows XP Pro i nece ni sa SP2 koji koristim.
