Not able to launch eclipse from the Dock. My operating system is Mac OS X 64 Bit.
The error says:
You can't open the application "Eclipse" because PowerPC applications are no longer supported.
I have installed Eclipse from this link: http://www.eclipse.org/downloads/?osType=macosx
One possible reason can be if you have moved the eclipse setup from where it is run. To verify, right click the icon at dock and choose Options -> Show in Finder. And Make sure Eclipse setup exists. If not, copy setup to that location and try running.
