I just received a laptop that givers me numerous Rundll32 errors. I have a full version of Win95 but am unable to reinstall over and upgrade version of Win95. Since I don't have the upgrade version, I cannot reload it. How can I remove the upgrade version without reformating or force it to allow me to install the full version. Since the upgrade version is full of errors, I would have to use Dos programs and commands to remove the older version.
