The information in this article applies to:


 * Microsoft Windows versions 3.0, 3.0a

SYMPTOMS
If you upgrade from Windows 3.0 to Windows 3.0a, and the SYSTEM.INI file contains an end-of-file character, the Setup program stops responding (hangs) without displaying an error message.

NOTE: This problem does not occur in later versions of Windows.

CAUSE
If the SYSTEM.INI file terminates with an end-of-file (EOF) character, the Windows Setup program stops (hangs). Most text editors (such as Edlin) terminate ASCII files with the &quot;1Ah&quot; (end-of-file) character. If you have used this type of editor to edit the SYSTEM.INI file, then Setup hangs when updating video or other OEM drivers. This occurs with either the DOS- or Windows-based Setup program.

WORKAROUND
Edit the SYSTEM.INI file with an editor such as Notepad or SysEdit that doesn't use the EOF character, or use a HEX editor that removes this character. Setup then operates correctly.
