--- Comment #3 from JB joachim.backes@rhrk.uni-kl.de --- I could solve the problem:
Reason: 1. /home was a symlink to /disk2/home 2. ~/Desktop/DL was a symlink to /home/backes/downloads, and /home/backes/downloads was mounted on /dev/sdc6
I reconfigured my filesystem so /home now is directly mounted /dev/dev/sdb1, and /dev/sdc6 is monted to /downloads, and the links ~/Desktop/DL now points directly to /downloads.
After this reconfiguration, the installer ElsterFormular-16.1.20150424p.exe runs flawlessly.
BTW: Obviously has problems to relove symlinks properly :-(
Thanks for your support.
