ok I've followed the installation manual by the book.
- installed the zend optimizer
- changed config.php as necessary
- set 777 cache and files folders
- uploaded all the files under /upload/ in binary mode (I've only renamed index.php to index_k.php and favicon.ico to favicon_k.php cause currently the site is live, using another support solution, so I can't just take it down till the new one kayako-powered is up)
- uploaded key.php in the root folder of the support suite, in binary mode as well.
I visit /setup/setup.php and I get an happy "License Error: Key file does not exist"
Starting uphill already...
