Article #29805: Class not registered error in Delphi 7 when dropping any component installed with dclisp70.bpl onto a form
Problem:
After installing the dclisp70.bpl package into the Delphi 7 IDE, I try to drop any component added by that package onto a form and I get a class not registered error message. Why does this occur?
Answer:
The Internet Solutions Pack contains NetManage components and is included
for backward compatibility with Delphi 2. The ocxs' that are required to use these components haven't shipped with Delphi since Delphi 3. We recommend that you
use Indy instead.
