Problem installing RTC 3.0.1 on RDz

We have a problem trying to install RTC on RDz. We have RDz 8.0.2 already installed and want to integrate RTC 3.0.1. Our Installation Manager is 1.4.4.

I have followed the instructions: first I have installed the RTC client using the launchpad. I selected the same package group as the RDz client and had no problems at all. But after the installation was finished, I started the IM and didn't have any new available installation package. Where can I find the Integration feature?
