Trying to load software but get error message -I need 98 SE

I just recently installed Win 98 SE - I previously had win 98 - I did so
because I purchased a Wireless Lan PCI adapter and when i attempted to
install I received a message that I needed Windows 98 SE - when I installed
98 SE - I attempted to install the Wireless Lan PCI adapter and again
received the error that I needed to have 98 SE or newer version of windows
installed on the computer - I checked the system properties and they list the
operating system as Windows 98 Second Edition - I assume there is a system
registry file that did not update and therefore that is likely preventing me
from installing the Wireless Lan PCI adapter - does anybody know what I need
to do in order to change all files to reflect the correct version of
windows??
