Ah, well, I saw a license.php file in the Install directory, but perhaps that one doesn't count.
As far as I know, the files have been correctly uploaded in binary form and I see them there on the server where they should be.
Currently I have gone back to a running version of V6 in a ../kalendar/calendar/calendar.php setup on our website. Beside it is ../kalendar/calendar7/calendar.php. When I attempt to install, I change the currently operating directory to /calendar6/ and the new one to /calendar/.
I point to our root/kalendar/calendar/install/index.php to try to initiate the installation, but fail to get a displayed page, just an unable to display the page message.
If I proceed to a ticket, what information would you need in order to be able to install the program on our server? An access username? password?
