• To obtain a current property, call the MsiGetProperty function.
• To obtain the current installation state, call the MsiGetMode function.
• To obtain the language for the current installation, call the MsiGetLanguage function.
• To set a property, call the MsiSetProperty function.
• To set the installation state, call the MsiSetMode function.
• To clear a property (setting it to Null), set the property's value to an empty string: "".
