Uninstall an Eclipse plugin when the "Uninstall..." button is disabled

Sometimes, for some reason, the "Uninstall" button is disabled in Help > About Eclipse > Installation Details (For example, after installing Aptana plugin, which forces the use of an older installer in Eclipse Galileo).

How is it possible to remove these plugins with "Uninst开发者_如何学Call" disabled ?

Try run eclipse as administrator. It worked for me.

Go into "Installation History" tab (in Installation Details), choose a previous state of installation, and click "revert"
