Unable to make GPG4Win 4.x portable

[Karel van Gruiten]

Hello!
Unfortunately my mail to gpg4win-users-en at wald.intevation.org was bounced, so I am trying to ask for help here:
I recently finally switched from the old 3.x series of GPG4Win to 4.0.4 doing a clean install which is working properly.
ButI am unable to create a portable installation from this, mkportable gives this output:
