Error Installing

What’s this mean

I’m trying to install n-track v. 3 build 1516 to a laptop running XP, plenty of memory, and hard disk space.

I’m getting the following message right at the beginning of installation:

16 bit Windows Subsystem

C:\Windows\System32\autoexec.nt. The system file is not suitable for running MSDOS and Microsoft Windows applications. Close to terminate.

Will not even run installer.

What gives, any ideas what to do?;en-us;314452;en-us;305521

thanks Phoo, but the problem was that the file was missing in the system32 folder folder. I found it and put a copy in the folder and was able to install n-track.
