A verbose log would be useful because of the timestamps so you can see where the time is going.
I assume the PDFs are referred to somehow from the MSI file otherwise there would be no need to access them. When you say "read", I suspect they're just being accessed for some reason. If the PDFs are available through an MSI feature such as access this feature from the DVD then it's my assumption that the install still goes through things like looking for existing files of that name, costing etc, so the log may show only a long time inside InstallValidate because accessing the DVD is slower. --------------- Phil Wilson On Tue, Dec 9, 2014 at 3:25 AM, Helmut Ziegler <scruffytec...@gmail.com> wrote: > Hi, > > we use WIX to deploy an application (100MB) that enables users to browse a > big collection of PDF files (around 4 GBs). > Installer (setup.msi) and PDFs are distributed via DVD.
