Comments
_Replacing line 569 in /administrator/components/com_civicrm/civicrm/CRM/Utils/System/Joomla.php with define('JPATH_BASE', $joomlaBase . DS. 'administrator'); // to make sure we analyse correctly in the Windows environment seems to solve the problem. I plan to create a PR, but this just flags the issue as a placeholder. Maybe someone else is working on the same file, and in which case can pick it up.
The issue occurs because line 12 of /administrator/includes/defines.php uses the directory separator to explode JPATH_BASE into its component parts. If, therefore, the separator between subdirectory and administrator directories is not the directory separator, JPATH_BASE won't be analysed correctly.
