NoteYou can have multiple Eclipse installations as long as they are located in different folders.
Download the correct Eclipse package from http://www.eclipse.org/downloads.
Extract the files to your local hard drive. The extracted zip file creates a folder named Eclipse.
Verify installed Eclipse version
Open the Eclipse folder where the extracted zip file is stored. Double-click the file eclipse.exe to start the Eclipse application. If the publisher cannot be verified, a dialog box will appear asking if you want to run the software. Click Run.
Browse the workspace folder where you want to store your projects. Click OK.
From the Eclipse menu, select Help > About Eclipse SDK.
The About Eclipse SDK window displays the version of installed Eclipse.
