If you use a commercial theme or plugin and need support, please go to their official support channel. In order to be good stewards of the WordPress community, and encourage innovation and progress, we feel it’s important to direct people to those official locations.
Forum volunteers are also not given access to commercial products, so they would not know why your commercial theme or plugin is not working properly. This is one other reason why volunteers forward you to the commercial product’s vendors. The vendors are responsible for supporting their commercial product.
Commercial themes are not supported here.
That being said, the documentation that came with your theme probably covers installation issues. The short version is this: install the theme manually by uploading the un-zipped theme folder to your /wp-content/themes directory using your FTP client.
Some general info on different ways you can install a theme: Adding New Themes Manually (FTP)
[edit] If you purchased the Canvas theme from WooThemes, they have a nice tutorial on theme installation here – https://docs.woothemes.com/document/installing-a-woo-theme/
