Unable to Integrate Rational Team Concert with IBM Integration Toolkit

Hi,

I am trying to install Rational Team Concert software by following the below procedure

1. Download the Rational Team Concert client from the Rational Team Concert download site: https://jazz.net/downloads/rational-team-concert/.
2. Start the IBM Integration Toolkit and select Help > Install New Software.
3. In the Available Software window, click Add.
4. In the Add Repository window, click Archive, navigate to the file that you downloaded in step 1 and click OK.
5. Ensure that Group items by category is selected, and then select Rational Team Concert Client (extend an Eclipse installation).

But the software is not being detected. I have verified the proper installables files present after unzipping the download. Request your help/suggestions

Thanks,

Binit
