#28 Unable to install in Eclipse 3.3.2

[Bobby]

I'm running MyEclipse 6 on Eclipse 3.3.2 on Windows XP SP 2 and am unable to install the plugin. It worked on a previous version of Eclipse 3.2/MyEclipse. I get this error when trying to visit the update site:

The current configuration contains errors and this operation can have unpredictable results.
Eclipse RCP Patch 1 for 3.3.1 (3.3.1.v20071002_331) requires feature "org.eclipse.rcp (3.3.1.R33x_r20070802-8y8eE8sEV3Fz0z0GlHJrXvTAUS)".
