Hello, We have found the same problem. We have a Powershell Custom Action, stored in BinaryTable modifying system information and therefore running in Deferred Mode in System Context. The Custom Action Hidden Target option is set and the property is included in the msiHiddenProperties table. This log snippet shows that the data is hidden by MSI (line 1) but InstallShield outputs the sensistive data twice, once with its own logging and once with the Powershell wrapper: . . . (Action=CAInstallEdefice_BOLCOMPlusPS,ActionType=11265,Source=BinaryData,Target=**********,CustomActionData=**********) MSI (s) (10:C4) [15:53:38:787]: Invoking remote custom action.

Is there any movement on this? Is there a setting to disable the InstallShiels logging? Thanks. ... View more
