Plesk 12 will not do it and if you reinstall it you get errors after installation. Maybe a bug but seems nobody is interested in answering my question before.
I tried to remove by
apt-get remove --purge sw-nginx
dpkg -r sw-ningx
Both of them display that is removed but after a new installation are the folders not created and maybe old files not overwritten if not deleted.
