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?

biber needs to "unpack" itself. In restricted environments the standard location (in the user temp-folder) is perhaps not accessible. In such cases you can set the PAR_GLOBAL_TEMP to some other folder. See https://github.com/plk/biber/issues/70
