In order to install screen-scraper on a machine, you'll likely need administrative or root access. Generally this is not the case with virtual hosting, so you likely will not be able to run screen-scraper on your server.

Oftentimes this won't preclude you from using it, however. A common scenario is to scrape data on a local machine, write the data to a CSV file, then upload it to a server to be imported. If you have a database running on the server, you may also still be able to run screen-scraper from a local machine, then insert the scraped data into your database using the technique we describe in our fifth tutorial.
