Properties Contained in MsiHiddenProperties have Their Value Written to the Log When Installation Includes a Feature Prerequisite

Title

Summary

Properties contained in MsiHiddenProperties have their value written to the log when installation includes a Feature Prerequisite

Symptoms

When including a feature prerequisite that contains a password, the value gets written to the install log even if the property is included in MsiHiddenProperties.
The expected behavior is that the property value should not be written to the log file.

Cause

This is an issue that has been submitted to Engineering. It is expected InstallShield prohibits the value of properties contained in MsiHiddenProperties from being written to the log, including situations where the:
? Properties are used as arguments for a .NET installer class.
? Installation contains a feature prerequisite.

Steps To Reproduce

Create a prerequisite which takes a formatted property as a command line argument:

"PROPERTYFROMPARENT=[PSWDTEST]"
Create a new BMSI project.
General Information > Enable Windows Installer Logging.
Add a Feature, Component, and a file to the project.
Application Data > Redistributables > Select the prerequisite created in step 1 to be included.
Associate the prerequisite with the Feature added in step 4.
Behavior and Logic > Property Manager > Add the following properties:

PSWDTEST = DefaultPassword1
PSWDTEST2 = DefaultPassword2
MsiHiddenProperties = PSWDTEST;PSWDTEST2
Add the following to the end of the value of SecureCustomProperties:

;PSWDTEST;PSWDTEST2
Build the installer.
Install product and prerequisite.
Open the log file and search for the value of PSWDTEST and PSWDTEST2 "DefaultPassword"

Resolution

The issue, IOJ-1754678, was reported to Engineering as a bug and was resolved in the InstallShield 2016 release.

Workaround

Add the prerequisite as a setup prerequisite rather than a feature prerequisite.
