Eclipse Indigo - Unable to upgrade m2e

Question

Folks,

I am trying to upgrade "Maven Integration for Eclipse" from the update site - http://m2eclipse.sonatype.org/sites/m2e.

When the repository site is entered, Eclipse shows me that the latest version available for download is 0.12.1.20110112-1712. However, when I start the install, I get an error about existing dependency. Here are the first few lines of the error:

Cannot complete the install because of a conflicting dependency.
  Software being installed: Maven Integration for Eclipse (Required)    0.12.1.20110112-1712 (org.maven.ide.eclipse.feature.feature.group 0.12.1.20110112-1712)
  Software currently installed: Eclipse IDE for Java Developers 1.4.1.20110909-1818 (epp.package.java 1.4.1.20110909-1818)
  Only one of the following can be installed at once: 
    Maven Integration for Eclipse 0.12.1.20110112-1712 (org.maven.ide.eclipse 0.12.1.20110112-1712)
    Maven Integration for Eclipse 0.12.0.20101115-1102 (org.maven.ide.eclipse 0.12.0.20101115-1102)
    This version of m2eclipse cannot be installed on top of the already installed m2eclipse. Uninstall the previous version of m2eclipse and try the install again. 1.0.0.20110607-2117 (org.maven.ide.eclipse 1.0.0.20110607-2117)
    This version of m2eclipse cannot be installed on top of the already installed m2eclipse. Uninstall the previous version of m2eclipse and try the install again. 1.0.100.20110804-1717 (org.maven.ide.eclipse 1.0.100.20110804-1717)
...

Ok. So I need to uninstall my older version of m2e first. I go to Help->About->Installed Software. I see the following two m2e features installed:

Eclipse IDE for Java Developers-->EPP Java Package-->m2e - Maven Integration for Eclipse 1.0.100...
Eclipse IDE for Java Developers-->EPP Java Package-->slf4j over logback logging 1.0.100...

The problem is when I select any of these two items, "uninstall" remains disabled. It seems the only way to uninstall it is to uninstall the parent "Eclipse IDE for Java Developers."

Can someone please tell me what I must do?

Thank you in advance for your help.

Regards,
Peter
