You need to start windows xp in safe mode, find a copy of the file ntdll.dll and copy it to the folder above. That file is corrupted. This may possibly indicate a pirated windows copy.

Please install delphi 6's D6_upd2_ent.exe D6_RTL1_ent.exe I'm too.

you can try to boot to xp's recovery console, by booting to the cd, after loading the files you must choose repair xp using recovery console, of course you will need the administrator password. if you succesfully boot to the console and find yourself at the c:\windows prompt type D: ***where d is the letter of your cdrom drive, if you dont know type MAP, that will show you what letter it is. after chaning to the cd drive, type: cd i386, and hit enter, you can then type: expand ntdll.dl_ c:\windows\system32, then hit enter, that will decompress the file and put it where it needs to be, if you dont mind loosing your data, I would suggest formatting reinstalling its the fastest way to go sometimes.
