Hardware and Software Requirements

EditWriter 5 and GenEDITS Plus 5 are based on Microsoft® Windows® versions XP and subsequent. The minimum hardware requirements are the same as those of the operating system used. If your computer runs Windows satisfactorily, it should do well with these programs.

The Edit Engine is provided for Microsoft Windows as a dynamic link library (EDITS50.dll) and for Linux as a shared object library (

EditWriter 5, GenEDITS Plus 5, and the Edit Engine are published for Microsoft Windows in 32-bit and 64-bit versions. The Edit Engine for Linux is published in 64-bit only.


Metafiles are portable SQLite databases. A single metafile is created using EditWriter and distributed for use by editing software such as GenEDITS Plus 5. This differs from EDITS40, which required two versions of metafiles: EditWriter 4 created and modified an editable metafile (.emf), and generated a run-time metafile (.rmf) for use by GenEDITS Plus 4.

Effective with North American Association of Central Cancer Registries (NAACCR) version 16C, an EDITS50-compatible version of the latest NAACCR metafile can be obtained from the NAACCR Web site. To download the latest National Cancer Data Base (NCDB) metafile, visit the NCDB Web site.
