Java errors

Some of our customers have reported encountering an error related to the Java Runtime Environment (JRE) when trying to install the latest version of SiteBuilder. Java is a programming language used to create the SiteBuilder application; the JRE allows SiteBuilder to run on your computer. Occasionally the JRE installation tool can't download the files it needs to complete installation, resulting in an error.

If you experience a JRE error when trying to install SiteBuilder, we recommend reinstalling Java and starting the SiteBuilder installation again.

Installing Java on your computer

  1. Download Java.
  2. Follow the instructions to install Java. (For assistance with your download, please go to Java's help pages.)

Beginning the SiteBuilder installation again

  1. Locate the SiteBuilder application file on your computer. You should've saved this file, called ysitebuilder.exe, on your computer when you downloaded the latest version of SiteBuilder. If you can't find the file, download SiteBuilder again.
  2. Double-click on the ysitebuilder.exe file to begin installing SiteBuilder.


If your version of SiteBuilder is older than version 2.8.9, you'll need to upgrade by downloading a new version of SiteBuilder rather than using the standard update process. Downloading will copy the updates to your computer, replacing your old version of SiteBuilder while leaving all of your work and your website intact. Please go to our SiteBuilder download page to get started. (Note that you'll be able to use the standard update process for future upgrades, and that Yahoo SiteBuilder remains a free tool. There's no charge for upgrading.)
