What is the reason for failing to write a full memory minidump from within another minidump?

I was analysing a full memory minidump (31GB) and had to run .imgscan /l to fix the module references.

Now I am trying to save it (following the advice given here - Is it possible to fix a full memory dump so that running .imgscan /l will no longer be required?) and here is the result:

0:000> .dump /ma "d:\tmp\cantestr52 - 06-09-2017\1.dmp"

    "No such interface supported"

What is wrong?

EDIT 1
