I'm working on a portable version of MikTeX and TeXstudio.
When I try to run Biber, the following error occurs:
..\MikTeX\miktex\bin\biber.exe: extraction of C:\Users\XXXXX\AppData\Local\Temp\par-55383237353136\cache-19a661c7206c3f371c207b98ac69231301395587/biber.exe (custom Perl interpreter) failed (errno=13)
The same error occurs when I start biber on the Command Line. pdfLaTeX on the other hand works fine.
What could be the reason for that?
