WSO2 installing developer studio problems in helios - eclipse

Question

I'm trying to install WSO2 developer studios and carbon in my eclipse Helios for developing API2 software, the first issue is the page of wso2 site for download Eclipse Helios with Carbon studio is down, the download links doesn't work. So I have to manually install carbon studio.
I manage to do it so, now I'm having problems trying to install the developer studio, this is the error stack.
Your original request has been modified.
"Smooks Tools" will be ignored because it is already installed.

From Dev Studio download page you can download latest Eclipse JavaEE luna + Developer Studio v 3.8.0 zip.
Furthermore, for certain WSO2 products (eg. ESB, APIM), there is a separate tooling distribution which is customized dev studio. You can download them from tooling link in each product download page.
