Chartz - Layers Extension was not installed

The plug-in cannot be installed.
Can I use it with version 5.3–ja of Wordpress?
If you can’t use it, please refund.

What’s the actual error you get? Are you sure that you are trying to install just the plugin and not the entire download?

What’s the item link?

Error Message is
