Connecting to Xerte files / courses + Scorm

Hello,

I think I properly installed Xerte, as I managed to some info and preparing lectures.

However I seem not be able to access anymore the content. What am I doing wrong?
http://localhost/xertetoolkits/preview.php?template_id=1

I would like to make the files in Xerte available to Scorm. It seems that a "patch file" has to be created. When I first open Xerte I did not have the option of creating such file.

Any help is appreciated.

Regards.
P.C.
