Uninstall of PSE 15 fails

When I try to uninstall PSE 15 an error message shows up and tells me that the uninstall failed. It tells me, I can find more information in a logfile. In this file I only find the following information:

2017-05-16 16:48:00:366 : ERROR vcfoundation::io::VCEndOfFile: WriteFile

race:    1 013127C2

   2 0130AB60

   7 01325FFC

   8 74058744

   9 7753587D

  10 7753584D

I don't really get, what this means. I already tried a reboot.

It would be nice, if someone'd help me
