C:\WINDOWS\SYSTEM32\AUTOEXEC.NT The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose close to terminate.
then gives you the option to close or ignore, and if you ignore it nothing happens. This happens when the AUTOEXEC.NT file gets deleted from the WINDOWS\SYSTEM32\ folder.
Some malicious malware/spyware/viruses are reported to damage these two files. If you haven't updated anything in a while, check the system integrity. If you regularly surf the internet it is EXTREMELY ADVISABLE to have a firewall activated and an up-to-date antivirus. Also, it greatly helps to use another browser than Internet Explorer, such as Firefox or Opera.
Usually, a back up of this file can be found in the WINDOWS\REPAIR folder. If this is missing, too, you can download it here. Unzip this into your WINDOWS\SYSTEM32 folder.
Another solution is to use this installation program will reinstall the missing or corrupt Windows XP system files command.com, autoexec.nt and config.nt. The absence or corruption of one or more of these files causes this"16 Bit Subsystem" error (use it at your own risk.) Fix for 16bit subsystem error:
