Properties

Purpose

This module provides assembly metadata and strongly-typed application settings for the Installer.Common assembly. It defines registry path constants and key names used for locating installed products, components, and configuration information related to DataPRO installations. These settings support Windows Installer custom actions that query the registry for installation state.

Public Interface

Common.Properties.Settings (internal sealed partial class)

• Inherits from global::System.Configuration.ApplicationSettingsBase
• public static Settings Default { get; } - Returns a synchronized singleton instance.

Registry Path Settings (all application-scoped, read-only):

Property Name	Type	Default Value
RegistrySoftwareInstalledProducts	string	SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Installer\\UserData\\S-1-5-18\\Products
RegistryInstallProperties	string	InstallProperties
RegistryDisplayName	string	DisplayName
RegistryDataPRO	string	DataPRO
RegistryDisplayVersion	string	DisplayVersion
RegistrySoftwareInstalledComponents	string	SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Installer\\UserData\\S-1-5-18\\Components
RegistryDataPROExeConfig	string	DataPRO.exe.config
RegistryInstallLocation	string	InstallLocation
DTSSuite	string	DTS.Suite

Invariants

• All settings are ApplicationScopedSettingAttribute, meaning they are read-only at runtime and must be modified via the .config file or by regenerating the settings.
• The registry paths target the S-1-5-18 SID (LOCAL_SYSTEM account), indicating these settings are designed for machine-level installer queries, not per-user installations.
• The Settings class is internal sealed, restricting access to the Installer.Common assembly.

Dependencies

• Depends on: System.Configuration.ApplicationSettingsBase, System.Diagnostics, System.Configuration attributes
• Depended on by: Cannot be determined from source alone (likely consumed by custom action classes within Installer.Common)

Gotchas

• The registry paths hardcode S-1-5-18 (LOCAL_SYSTEM).
