The Nokia WRT Extension for Dreamweaver can be downloaded from the Forum Nokia website or from Adobe Dreamweaver Exchange. Once the extension has been saved to a suitable local folder, with Dreamweaver closed, double-click the file. Adobe Extension Manager CS4 will open displaying the license agreement (see Figure 1).

Click Accept and the extension will be installed. Once installation is complete, you can close the extension manager and start Dreamweaver.
If there is a more recent version of the extension available, the Nokia Update Manager dialog box is displayed (see Figure 2). I recommend that you click Download and Install Update to ensure you have the latest version of the extension.

The update process starts Adobe Extension Manager. You will now receive a warning that the update files are of the same name as the existing files, click Yes to overwrite the files. Once the update is complete, you will be asked to close and restart Dreamweaver before the update will take effect. Before closing Dreamweaver you will have to close the Nokia Update Manager dialog box.
Java Runtime Environment (JRE) 1.5 or later must be installed to enable the packaging of widgets and their deployment to a S60 device. The latest JRE can be obtained from the Free Java Download page on the Sun Java website. Mac OS X users should run Software Update, found in the Apple menu.
Note: If you are installing an update to the extension on Mac OS running FileVault, it is possible that the installation of the update will fail. If you encounter this problem, install the update manually by downloading the upgrade using the link in the Nokia Update Manager dialog box, as shown in Figure 2, and then repeat the installation process.
