Doug,

The "#code-sign aplication" directive lets you code-sign your application file(s) - DLLs, EXEs, etc. The Project Settings -Digital Signatures Tab gives you control over the code-sign for your installer and uninstaller (compiler variables are supported).

When requesting a Comodo certificate, I would suggest to use the default settings.

This is an interesting video:

Hope this helps!
