I worked through this code and wrote it out myself and then I downloaded the websites source code. I keep coming up with the same error code:

JInstaller::install: File '/mnt/stor1-wc1-dfw1/369718/369719/www.oldwestmovies.com/web/content/tmp/install_49c7fcc97db00/com_scrape/scrape.php' does not exist.

What is the problem with this components zip file for installation?

In response to your question, the file scrape.php is saved as com_scrape.php. The XML file and install script both describe the file as scrape.php, so when you attempt to install the script it can't find scrape.php. Simply rename the script to scrape.php and zip the component and it will install in Joomla.

However, after fixing this issue, the component shows that it scans a html site and displays the results, but after trying several diffent sites, it still shows no results. I have changed the url to match the url my site is at.

I haven't turned on debug yet, but so far it's not worth the effort. There are other scrapers that put their results into a csv file and can upload those to my directory.
