My recommendation would be to add an immediate custom action in the InstallExecuteSequence table before CostInitialize that adds "temporary" rows to the DuplicateFile table and "temporary" rows to the Directory table. You would also need the following authoring:
<InstallExecuteSequence> <DuplicateFiles/> </InstallExecuteSequence> <EnsureTable Id="DuplicateFile"/> You should also save the parameters for your custom action so that they can be retrieved when repairing or uninstalling so your dynamic directories can be cleaned up/upgraded as appropriate. See http://www.joyofsetup.com/2007/07/01/semi-custom-actions/ for the concept of using native functionality to do non-native things. This tends to be much more authorable and reliable than trying to implement deferred actions and getting rollback, etc. working in every case of repair, install, removal, both kinds of upgrade, etc. Such an immediate action can be tested using Lux as well, so you get testability as a bonus. -----Original Message----- From: Keith Hassen [mailto:keith.has...@gmail.com] Sent: Wednesday, July 07, 2010 6:03 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Dynamic directory creation Hi, I am faced with a problem of building an MSI that requires a set of directories to be created during installation. These directories are all prefixed with a common string (eg "folder") followed by a sequence number (eg "01") so that their final construction might be something like "folder01", "folder02", etc. I need to place the same executable in each of these generated directories, but the number of directories isn't known until install time. I would like to prompt the user for that number during the setup and then dynamically build the directories. My original assumption was that WiX simply couldn't do this task because of the dynamic nature of the problem. I assumed that I'd have to write a batch script that would do this work for me: my approach was to always generate 1 directory, and then use a CA to invoke a batch script that would copy the directory as many times as was needed. I thought I'd post this problem to this list to see if there were other solutions (using WiX or otherwise) that might be cleaner or more effective.
