Eclipse problem when install new software

I'm using Eclipse 3.6 (Helios) for mac os X. I downloaded from the Eclipse download page, unzip and put it in Applications folder. Then, i start the Eclipse and choose the workspace (the default, Documents/Workspace). After this, i tried to install new software by going to Help->Install New Software. The problem is 开发者_StackOverflow中文版that a error occur with the following message: "Cannot complete the request. This installation has not been configured properly for software update. See the error log for details."

And the error log has: "Could not locate the running profile instance. The eclipse.p2.data.area and eclipse.p2.profile properties may not be set correctly in this application's config.ini file."

I'm trying to do this because i wanna install ADT for android developments (and i can't perform the very first step of the "how to").

What i can do to fix this??

Thank you in advance

Most likely, this is caused by a bug in an old version of The Unarchiver that corrupts the default profiles included with eclipse. Upgrade to the newest version of The Unarchiver, extract eclipse again, and everything ought to work.

Generally this is because the links for adding dependency packages aren't setup in Eclipse. Ensure that http://download.eclipse.org/eclipse/updates/3.6 and hxxp://download.eclipse.org/eclipse/helios (replace xx with tt) are listed under Available Software Sites (under Help -> Install New Software). Once theses are present Eclipse should be able to download all the dependancies it needs for ADT.

I had the same problem. Eventually I downloaded a different package (actually I tried a couple of different versions, they both had different bugs). Give that a burl, and if it works you just install the plugins for the work you're doing.
