Installation problems under Windows XP

We've heard a few reports that installing Code Development Systems under Windows XP occasionally fails with the message:

"16 bit Windows Subsystem
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.

In others, the installer doesn't allow users to click the "Setup" button to start the actual setup process.

The message signals a rare problem caused by one or more changed files in Windows XP. If one of the command.com, config.nt, or autoexec.nt files are altered or missing, setup may not proceed.

There is a fix: restore the files from the original Windows install media, or (in the case of the .nt files) recreate them.

See Microsoft's help article describing the problem and solution.
