installation problems ?

Hi
I am having installation problems.
I have downloaded the demo and I go to install it and it give me an error.
Is this program intended for Windows XP users ?

If so I get this error.

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

Try downloading the setup file at http://www.getgopher.com/temp2004 . Run it. Then when you first run Gopher, click Ok to get past the error windows and go to Options | Database tab. Click the folder button and then double click on the GOPHER2003.GDB file.
