Thanks for asking.
I am quite confused and concerned with with your question and screenshot. Can you please elaborate exactly what your are trying to do? The screenshot you have shared is to publish a theme into WordPress.org theme repository. Which let's me to come at two situations.
Publish X Theme at WordPress.org theme repo: In case you are trying to publish our theme at WordPress.org theme repo, let me tell you that it's absolutely not permissible. Please take a look at Themeforest licence guidelines. https://themeforest.net/licenses
Trying to install X Theme on WordPress.com: In case you are intended to install X Theme on WordPress.com and mistakenly opened up WordPress.org website, then please make sure to unzip the file you downloaded from Themeforest and upload the installable zip archive. Here is a tutorial on installing X Theme.
Please clarify as I am kind of confused with the question.
