I've noticed problems when installing the extension resulting in "Warning JInstaller: :Install: Can't find XML setup file" and "Error Unable to detect manifest file." I've tried to install on various sites with the same effect.
Anything I'm missing here?
Thanks for your support and hint
I got it - the package file is within the ZIP file in the folder "Package Install"... Now everything runs like a charm. I simply edited my post, since may other new users are looking for the same solution...
