16 bit application under Windows XP Professional

[Sri]

When I bring up a 16 bit Application VB3 under Windows XP
I get the following error - The system file is not
suitable for running MS-DOS and Microsoft Windows
applications. Choose 'Close' to terminate the application.

I tried the following suggested under this hyperlink
http://support.microsoft.com/default.aspx?scid=kb;en-
us;324767 and got the 16 bit app to work. However
everytime I reboot the machine I seem to running into the
problem again where the 16bit app will not work.
Any ideas.

[technical advice]

Do you have some old software that runs at startup that
may be causing the problems you describe?

Take a look at the autoexec.nt file referred to and see if there is any
other line getting put into it. Also in the properties of the shortcut
to your VB3 program look under the Program page, click Advanced to make
sure it is not using some custom version. See if the entry that is
causing trouble reappears after running the program (if so it needs
amending or transferring to a later VB version)
