The functions are divided into three groups.  One group deals with the Per Application Paths Key, another group deals with the Application Uninstallation Key, and the final group deals with the Application Information Key.  As you look at each group's registry key, note that the root key will depend on what the ALLUSERS system variable is set to.  If ALLUSERS is FALSE, or if you've called ProgDefGroupType(PERSONAL),  the root key will be HKEY_CURRENT_USER.  Otherwise, the root key will be HKEY_LOCAL_MACHINE.

The Per Application Paths Key stores path information enabling Windows to find your application's executable files.  Here is the Per Application Paths Key:

<root key>\Software\Microsoft\Windows\CurrentVersion\App Paths\<per application paths key>

The functions in the Per Application Paths Key group are as follows:

CreateInstallationInfo()
RegDBDeleteItem()
RegDBGetItem()
RegDBSetItem()

 The Application Uninstallation Key stores information which enables uninstallation functionality.  Here is the Application Uninstallation Key:

<rootkey>\Software\Microsoft\Windows\CurrentVersion\Uninstall\<INSTANCE_GUID>

The functions in the Application Information Key group are as follows:

MaintenanceStart()
RegDBDeleteItem()
RegDBGetItem()
RegDBSetItem()

 The Application Information Key stores information about the application.  Here is the Application Information Key:

<root key>\Software\<company key>\<product key>\<version key>

The functions in the Application Information Key group are as follows:

CreateInstallationInfo()
RegDBGetAppInfo()
RegDBSetAppInfo()
