Error Message When Opening an FME Workbench

Problem

When opening an FME workbench, the following error message appears:

File C:\Program Files (x86)\FME2018\metafile\GEONISDATASOURCEFORMAT.fmf could not be opened

Cause / Solution

GEONIS Data Converter had not yet been installed, so the corresponding transformers could not be found. After installing GNDC, the error message no longer appears.
