Your app is probably accessing HKEY_LOCAL_MACHINE which is mapped
to $prefix/etc/mono/registry/. This dir is usually not writable
by non-root. Note that even GetValue is touching the file system.

You can change this path by setting the env var MONO_REGISTRY_PATH
to a directory the current user full access for.
