Joomla itself, not our software. Joomla is responsible for the upload, unpacking of the package and installing it.
While this is a Joomla issue we have already compiled
a document of everything that can go wrong during extension installation and how to solve it. This document is universal. It applies to all extensions by all developers, not just our own.
Based on your description the first things I'd look would be the upload_max_filesize and post_max_size in PHP's configuration (tip: look in System Information to see the value PHP sees) and whether there is available disk space (ask your host
even if your control panel says you do have enough space; many hosts only make increments of that space available upon request).
