Mork,
MyEclipse 2015 is a unified product. Users no longer need to download separate installers for Pro/Blue/Bling/Spring versions. Access to the features depends on the corresponding license applied. Once you install MyEclipse 2015, apply your Pro license and you will have access to all the Pro specific features.
Let us know if you see any issues.
