The latest version of MDT PE is now compatible with 64-bit Windows environments. The underlying Eclipse version has been updated to 4.9. We strongly recommend updating your MDT.
Another significant change is that the MDT SW5 Support Plug-in is now called MDT 5J Extension. The MDT 5J Extension 1.6.0 plugin is compatible with MDT PE 4.1.0 and supports 64-bit Windows environments.
