I checked these question/answers already, but they did not address my issue:
- GRASS plugin missing from QGIS 2.14.3 Essen in Ubuntu 14.04
- How do I get grass plugin working in QGIS for Windows?
I am on a Windows 10 sytem, 64 bit. I installed QGIS 2.18 (also 2.14 and 2.16 to try to resolve the issue). The GRASS plugin is simply NOT THERE. So, when I go into the program files of QGIS 2.18 and look in the apps folder it says GRASS 7.2.0 is installed. For QGIS 2.16 the apps folder has GRASS 7.0.4. Finally, the QGIS 2.14 has GRASS 7.0.4.
I am not a developer, so I cannot troubleshoot at the code level...
