Collaborator plugin install error on RTC

I can't install collaborator plugin v9.5.9502 (ccollab_client_9_5_9502_001_update_site.zip) to RTC Eclipse client 5.0.2.

I have the following error:

Cannot complete the install because one or more required items could not be found.
Software being installed: Collaborator 9.5.9502.001 (com.smartbear.collaborator.base.feature.feature.group 9.5.9502.001)
Missing requirement: Collaborator - Resources Support 9.5.9502.001 (com.smartbear.collaborator.ide 9.5.9502.001) requires 'package org.osgi.util.tracker [1.5.0,2.0.0)' but it could not be found
Cannot satisfy dependency:
From: Collaborator 9.5.9502.001 (com.smartbear.collaborator.base.feature.feature.group 9.5.9502.001)
To: com.smartbear.collaborator.ide [9.5.9502.001]

The RTC Eclipse IDE is the RTC-Client-Win-5.0.2.zip version.

I would be pleased if anyone have any clue about it.
