In order to upgrade from version 3.x to version 4, you'll need to install version 4 fresh using one of our installers, accessible from this page. This is necessary because we're now using an upgraded version of the Java Runtime Environment, which can't be upgraded using the normal "Check for updates..." method of upgrading within screen-scraper.

Those who licensed screen-scraper Professional Edition prior to the release of version 4.0 are entitled to a free upgrade. Please note that version 4.0 of the Professional Edition lacks some features that were available in version 3.0 (and subsequent alphas). If you licensed screen-scraper Professional Edition before version 4.0 was release, just send us a support request indicating such. As part of this upgrade you'll be entitled to a license for screen-scraper Enterprise Edition, but will not be entitled to the phone and email support that current licensees of the Enterprise Edition get.

Steps to upgrading to version 4.0 from any version 3.x or below.

1. Make a back up of your existing installation and export your scraping sessions and scripts by following instructions here.

2. For Windows users, uninstall the old version version using Add/Remove Programs in the Control Panel.

3. Download and install the latest version from this page.

4. Import your work into your new installation following instructions on the lower half of this page.
