"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."

The reason that this error is occurring is due to the AUTOEXEC.NT file not existing in the System 32 folder. It appears that many preventative software pieces such Pop-Up blockers, spyware, adaware programs are recognizing this file as being associated with viruses and removing the file.

To fix this error,right click on the attachment AUTOEXEC.NT located below under "Article Attachments"; then click on SAVE TARGET AS, and save it into the System32 folder. This can be completed by saving the file into C:\WINDOWS\system32 if you are running Windows XP.

Then proceed to open up the program again. You should now be able to open the program without seeing this error.
