@Guido, I am not sure I understand the restrictions in the answer. I believe I had more than one Eclipse Client installed on my machine using IM. As far as I remember IM warns you if a package is already installed. However it does not prevent you from installing, as long as you pick a different installation folder (or Eclipse to extend). This is by the way necessary if you want to install the IM RTC Eclipse client as well as install it into tools like RAD.

If you have installed the IM version, I think you should be able to P2 install or any other Eclipse way of adding other extensions if you like.

You can also use P2 Install into Eclipse, however, please be aware that at least in 3.0.x there was an issue with conflicting plug in versions or dependencies that came up after P2 Installing RTC into an existing Eclipse. This prevented you from installing other extensions afterwards. I am not sure if this is still an issue. This did not affect the IM install.


In general I typically use the zipped version of the RTC Client just for convenience. I have at least 7 of different versions installed in parallel.

With respect to plugin development I have so far used the zipped RTC Eclipse Client. Sometimes it is more convenient to use a P2 install, because that (like IM) gives you the ability to install into a newer Eclipse version. This can help if the plugin development has been enhanced. I have used that in the past too. 

Kaushik, you can find that out easily on your own. Please be aware that the getting started tab of a downloadable version always contains a link to the system requirements https://jazz.net/downloads/rational-team-concert/releases/4.0?p=gettingStarted

This also contains the supported Eclipse versions.
