During the installation of a new program (including Windows 98), files on your hard disk may be detected and replaced with older versions. If a newer version of a file is detected by Windows 98 Setup, a version conflict occurs.

When you install Windows 98, this prompt does not appear and newer files replaced by Windows 98 Setup are automatically backed up to your hard disk for compatibility purposes.
For example, if you upgrade a Windows 95-based computer that uses a newer version of the Commdlg.dll file to Windows 98, the newer Commdlg.dll file is backed up and the older Commdlg.dll file is copied to your computer.
