I keep getting this error:
D:\Lego\ldraw\mklist.exe
C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running
MS-DOS and Microsoft Windows applications. Choose ‘Close’ to terminate the
application.
[Close] [Ignore]This error is sometimes caused as a result of installing Windows XP SP2.
Some of the LDraw software used for the installation makes use of 16-bit Windows technology which requires a valid AUTOEXEC.NT file to be present in the system. This file, which is part of the Windows 16-bit subsystem as it ships with Windows 2000, Windows XP, and Windows Server 2003, normally resides in the "System32" subdirectory of the Windows installation directory.
Installation of Windows XP Service Pack 2 on an otherwise "healthy" Windows XP system may delete the AUTOEXEC.NT file. As a result, when trying to run certain applications which make use of 16-bit technology an error message like the following may be displayed as the above error message.
The error message can be misleading, because it is displayed even if the AUTOEXEC.NT file is actually missing.
To verify whether you have the file, type "%windir%/system32/" in the address bar of an Explorer window. If there is no AUTOEXEC.NT file proceed as follows:
1. Browse to "%windir%/repair/" (usually "C:\WINDOWS\repair")
2. Right-Click and Copy the AUTOEXEC.NT file
3. Browse to "%windir%/system32/" (usually "C:\WINDOWS\System32")
4. Right-Click inside the window and Paste the file
The error condition described here may also be the result of corruption of the AUTOEXEC.NT file, in which case the above procedure may be helpful to restore a valid file.
