Can we use also this theme into Magento 1.9.x?

Hi Mike,
We see that you purchased Megamall theme for Magento 1. Meanwhile, the UB Megamall is a theme for Magento 2, which can not be used for Magento 1.x.

Hi Mike,
For all our M1 themes including Megamall you purchased, you can use on unlimited sites. 
We applied changes for our Magento 2 products only. The license grants you permission to use each M2 extension built-in our Magento 2 theme on one domain only.
Hope that helps.
