I ran into this same problem when trying to use OpenFileDialog(). You need to make a new thread with a different appartment type for the UI to show. Here is a sample of what I did to make it work.
// create a new thread with appropriate apartment state to launch UI FileBrowser fileBrowser = new FileBrowser(session); Thread worker = new Thread(fileBrowser.Show); worker.SetApartmentState(ApartmentState.STA); worker.Start(); worker.Join(); Then implement your code in the FileBrowser class displaying the OpenFileDialog using the Show method. -Mike -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/OpenFileDialog-fails-in-Win7-tp5538592p5542494.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
