Open Notepad or Wordpad
Click File
Click Open
Browse to C:\WINNT\System32 directory
Open the file CONFIG.NT
Look at the bottom of the file for the following syntax:
device=%SystemRoot%\system32\himem.sys
If it is not there add it to the file
Click File
Click Save
Close Notepad or Wordpad
This line may exist but be proceeded by a "REM", which prevents it from being read. Remove the "REM" if this is the case.
If there are other "devices" specified, add "REM" to the line to prevent it from being used in the DOS settings during the install. It is possible to remove the "REM" once setup is complete.
Similarly, check if the statement, "lh %SystemRoot%\system32\dosx.exe," exists in the AUTOEXEC.NT file
Expand HIMEM.SYS, DOSX.EXE, or both from the Windows NT or XP setup disks or CD- ROM disc if either or both are missing from the SYSTEM32 directory
Try setup again
