Benim icin tum zamanlarin en iyi programi AutoCAD dir. Cok degisik kesimler tarafindan kullanilan ve artik endustri standardi sayilan baska program yoktur herhalde. Profesyonel duzeyde kullanicisi oldugum bu program + ve - leriyle yine 1 numara olmayi surduruyor. Bu kadar yaglamadan sonra ise koyulalim.

Su an DLL dosyasinin icindeyiz. Tarih 07D1071E ile karsilastiriliyor.

07D1 = 2001, 07 = 07, 1E = 30 --> 30/07/2001 tarihinden ilerideysek hata veriyor. Yapmamiz gereken 07D1 degerini degistirmek. Patch yaptiktan sonra tekrar ayni hata cikiyor. Yukarida yaptiklarimizi aynen uygulayalim.

Simdi de “Fatal Error” tarzinda garip bir hata verdi. Yaptigimiz patchlere gore boyle bir hatanin olmamasi gerekirdi. Demek ki program patch edilgini anliyor. [faults on] -->

Program 653DEE2C de JUMP yapmayip RET ile geri donuyor. Ama JUMP yaparsa 6375FBEC memory bolgesine A866F8 degerini yazacak ve “fatal error” vermeyecek. Patch yaptiktan sonra tekrar deniyoruz. Ilk bastaki hata tekrar ortaya cikti.
