How to install and configure a COM?

Using the "Extract registration info from native library" option on the com file added in Files and Folders page

The first method is to use the "Extract registration info from native library" option on your COM file added in Files and Folders page. In this way, Advanced Installer simply extracts the COM registration registries and adds them in Registry page of your setup project. Also the COM registration data is reflected/displayed in COM page too, but in fact, at install time the COM registration simply consists of the installation of the above COM registries.

This method has automation support: you can use /RegisterFile command with -registration_type Extract switch option.

Manually defining and adding in COM page all the com registration settings

The second method consists of manually defining and adding all the com registration settings in COM page. Also, the COM registration settings defined through this approach will be configured at install time by the Windows Installer predefined support, i.e. using the MSI's Class table, TypeLib Table and Complus table.
