I want to upgrade from OSR2 to Windows 98 using the full installation disk. However, a message "cannot upgrade with this version of setup, please obtain upgrade" appears. Is it possible to upgrade using the full disk or not. Please note that a similar message appears when you try to upgrade from OSR1 to OSR2, but it is possible to modify the setup.inf to to this. Is there a way round the full 98 installation program to bypass this message so that you can carry on with the installation. There is a way, but how, so get your thinking caps on.
