I am trying to install Cadkey 98. I already know that it is too old to install directly. It is no longer supported by teh original manufacturer.
My client advised we could revert the OS back to Windows 98 in order to install teh software.
However, I don;t know if that measn my entire computer will then run in the older OS version or the newer. I don't want my computer running the old OS.
How can i install this older software and still keep my current OS?
