looking for theme installation guide and video.
Business and Professional Services theme

Unfortunately these are general forums - If you are having issues with a theme then you need to ask the author of that item (Look on the item page above the main image and there is a “support” tab).

Note that “installation” is not a requirement of support - while some authors may offer to help they are not obliged to do so.

You should begin by reading the documentation that comes with re theme which will cover some of the basics although not necessarily actually installing a theme.
