I've got SMFHacks.com set up as a package manager server, but can't find the store as an option to download.
...so I downloaded the mod to my workstation, then uploaded it to my beta site and my active site.
I created the temp (with a lower case t) folder under the Package folder, ensured that both folders were set to 755, and received the same error. I upped the anti again, and moved the folders to 777 permissions, and still no love. (fourm directory also set at 755)
I tried the manual route again and found I still don't have the correct rights:
Forbidden
You don't have permission to access /forum/Packages/storeinstall2.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
