This was indeed very helpful. I started using conditions such as (&Feature = 3) to detect feature's installation and (&Feature = 2) to detect feature removal. Big improvement in WiX script structure comparing to what I inherited.
Thanks a lot. -----Original Message----- From: Blair Murri [mailto:os...@live.com] Sent: Tuesday, January 28, 2014 5:08 AM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] finding out what features are being installed ADDLOCAL doesn’t have to be set. When costing is done in the UI sequence, the result of that costing will be placed into the family of properties that includes ADDLOCAL in order to communicate to the execute sequence which features are to be changed and how (which causes things like feature conditions, installlevel, and parent/child relationships between features to be ignored in the execute sequence’s costing). If none of those properties are set when the execute sequence starts costing, then those other means of determining what to do for each feature are used (as they would have been in the UI sequence). If you want to know what the action and status of each feature are there are both APIs and a conditional syntax that will give them to you without having to depend on properties like ADDLOCAL. Look at pages like http://msdn.microsoft.com/library/aa368012.aspx (Access Prefixes section) when using the Condition type in the database (such as in the sequence tables) or when using the MsiEvaluateCondition() function in a CA, or more directly by using the MsiGetFeatureState() function in a CA. Blair From: Marek Mielcarek Sent: Monday, January 27, 2014 3:06 PM To: General discussion for Windows Installer XML toolset. To learn what features are being installed I try to examine ADDLOCAL which is a standard parameter that can be passed to MSI. I use the following line in my WiX xml to do that: <SetProperty Id="FEATURELIST" Value="[ADDLOCAL]" After="CostFinalize"/> Then, inside InstallExecuteSequence element I am scheduling custom action which uses my local FEATURELIST property. When I launch the installation with UI (although I have no dialogs), the FEATURELIST holds names of all features separated by comma. When I launch silent installation (i.e. use /qn switch) the value of FEATURELIST is blank. In both cases I do not specify ADDLOCAL, which instructs MSI to install all available features. Why these 2 cases yield different values? I'd always expect the same behavior regardless of /qn switch. If that is not the right way, can somebody please suggest a reliable way of checking what features are being installed ?
