Unable to install Google App Engine Plugin (Eclipse 3.6)

I've followed these instructions but I'm unable to install the GAE plugin on Eclipse 3.6 Helios.

Any ideas what coul开发者_Go百科d be wrong and how to fix it?

This is a clean install of Eclipse, the only added features are the Eclipse Web Developer Tools per instructions.

This is on Windows XP.

Don't make it more complex than needed. Use the PlugIn: GAE Plugin Instructions

I fixed it by installing Eclipse for Java EE Developers

The version for different types of eclipse is different for Google App Engine Plugin. Try to use different version of plugin as required by your eclipse . I Have used http://dl.google.com/eclipse/plugin/3.4 for my Hellios Version eclipse and it is working file after installation . Do not forgot to researt your eclipse in clean mode after installation of plugin.
