MsiHiddenProperties property

The MsiHiddenProperties property may be used to prevent the installer from displaying passwords or other confidential information in the log file. To prevent a property from being written into the log file, set the value of the MsiHiddenProperties property to the name of the property you wish to hide. You can hide multiple properties by specifying a string of property names delimited by semicolons (;).


When the Debug policy is set to a value of 7, the installer will write information entered on a command line into the log. This makes public properties entered on a command line visible even if the property is included in the MsiHiddenProperties property. This can make confidential information entered on a command line visible in the log. For more information, see Preventing Confidential Information from Being Written into the Log File.
