[GAP Forum] Package Digraphs on Windows

[Hebert Pérez-Rosés]

Hi again,

I uninstalled GAP 4.11.1, and installed it again as an administrator (also
using Windows 10). Then I ran it as an administrator, but the error
persisted. Tomorrow I will try to build the digraphs package as you
suggested (and check whether everything else keeps running), and I will let
you know.

If it doesn't work, then I will try the online option.

Thanks a lot for your help.
Hebert
