Not at all. It only needs to compile a package. That's where all the
components are kept. Delphi can load multiple packages at once, so you
don't need to disturb the Delphi-supplied packages to install new
components.

Delphi creates a unit for you. You need to put that unit in a package.
Delphi provides one named dclusr, which you're welcome to use for that.
Otherwise, you can create your own new package. Add your COM unit to the
package's "contains" section, compile the package, and install it.

Thank you.

One last question - what is the COM unit ?

The only unit you have. The one the type-library importer created for
you. (ActiveX is a subset of COM.)
