Thanks Phil!
I created a verbose log via
"msiexec /i "setup.msi" /l*v "c:\temp\wix.log""
The log is quiet while the files are being accessed :-(
Here is a line of ProcessMonitor that shows the read Access at 15:15
15:15:51,0348430 msiexec.exe 24212 ReadFile
Y:\data\tomcat\webapps\data_dvd1\100219.pdf END
OF FILE Offset: 689.656, Length: 4.096
In the verbose log there are entries at 15:13

and then at 15:22 there are some messages that say that the files
referenced are not available (which is right, as they are on another DVD)

That all occurs in the phase "Updating component Registration"
And yes, the PDFs are referenced in the installer. They can be installed
optionally (which is not an option for most users as they don't want to
have GBs of PDF on their hard disk).
The "Typical" installation leaves all PDFs on the DVD and just installs the
application.
At the moment there seem to be two explanations for the behavior of the
installer.
* This read accesses are by design of the Windows Installer
* Our installer has a bug, so that it does the right thing in the end but
with a lot of unnecessary work ...
If it is the latter I'll have to see if I can create a small example that
reproduces the behaviour. The current installer is far too big to track
anything down ...
Any hints are welcome, though...
