When you try to reinstall or upgrade the copy of Windows 95 on an IBM Aptiva 710 computer, you may receive the following error message while Setup is analyzing the computer:
Setup: Error SU0507

The following problem occurred while Setup was analyzing your computer:
SDMErr(8037001b): Detection function returned a DMS error.
DMSError: This computer cannot be upgraded from Windows. Please shutdown Windows and upgrade in MS-DOS mode.

Setup cannot continue and will now close.
If you restart the computer in MS-DOS mode and try to install Windows 95, you may receive a general protection (GP) fault error message during the detection portion of Setup. If you ignore this error message, Setup continues and finishes correctly.


When you run Setup from within Windows 95, the computer's BIOS prevents Setup from reliably detecting all the installed hardware in the computer.


Restart your computer in MS-DOS mode and then run Setup. If you receive a GP fault error message, ignore the error message and continue.

For information about a possible BIOS upgrade to eliminate this problem, please contact IBM.


This issue has also been reported on Compaq Presario CDS 520 486SX2/66 computers.
