installation problem- request manual installation for SourceCoast

That error is stating that the installation XML file from one of our sub-packages can't be copied. The directory that the file is being copied to is /libraries/sourcecoast Can you make sure that the /libraries directory is writable by Joomla and, if the /libraries/sourcecoast/ directory exists already, that it too is writable?

Once your permissions are fixed up, the installation should work as expected.

Thanks,
Alex
