Error: Please check for sufficient write file permissions
Your Magento folder does not have sufficient write permissions, which this web based downloader requires.
If you wish to proceed downloading Magento packages online, please set all Magento folders to have writable permission for the web server user (example: apache) and press the “Refresh” button to try again.
Thats what it tells me. I went into my base directory (httpdocs) and ran chmod 777 -R *
So everything should definitely be writable. But alas, I still get that message!
