Downloaded eclipse Europa on laptop as it has 2GB RAM and latest eclipse makes it run slow.

From http://archive.eclipse.org/technology/epp/downloads/release/europa/winter/eclipse-java-europa-winter-win32.zip

Unzipped, clicked eclipse.exe See this error:

Can I get java 5? un install Java 7 first? Any easy way to keep both and run old eclipse too?
