For both setups: If you followed the default installation instructions you now have 3 files in your web directory: full.zip, index.php and install.php
As the full.zip should be removed after installation, the easiest solution is the chmod the file to 777 (full rights for everybody).
This should allow the install.php script to read and unpack the zip file.
