W2K3 SP2 German (out of the box installation)
running inside of a XENServer or VMWare
mount the iso-image ZCM_10.2.0.iso and run setup

Installanywhere extract some files and presents the attached dialog-box after a few seconds.
"Waehlen Sie einen anderen Speicherort aus" => "Please select another storage area".
After clicking on "Auswaehlen" and selecting a directory on the C: drive the process starts again and ends in the same dialog-box...

What I'm missing?

On C: is about 30GB free space
Downloaded the iso a week ago and yesterday again with no effect. Same result with both downloads.
