Hi,
You can't.
If you have specific request about it, you can potentially use the "contact us" form.
BUT, the main idea is that when you have an active subscription you can download HikaShop package and keep a copy in your computer.
When you install a component in your website (or updates), it is always a good reflex to still have corresponding install package in a computer in order to restore (or duplicate) your website.

By the way, do not send me private message, use the "contact us" form instead.
