I installed RAD 7.5 and found out that IBM is not as good as I thought of it. RAD thing has it's own "install manager" which doesn't seem to resolve any dependencies. Does anyone know how to enable standart eclipse's software installer and/or Eclipse Marketplace?
You should be able to enable "classic install" in the preferences and then use the traditional installer to bring in 3rd party features. Even so, you'll still need to use IBM's installation manager to apply fixes, upgrades and new components from IBM/Rational.
