GRASS GIS Plugin not loading in QGIS 3

Geographic Information Systems Asked by Ratnanil on March 8, 2021

When starting up QGIS 3.2.2 (also tested with 3.2.3), I get the following message in the “Plugins” Log Message Window:

2018-10-18T08:03:48     WARNING    Failed to load C:/OSGEO4~1/apps/qgis/plugins/grassplugin7.dll (Reason: Cannot load library C:OSGEO4~1appsqgispluginsgrassplugin7.dll: Das angegebene Modul wurde nicht gefunden.)

And sure enough, I cannot use the GRASS GIS Plugins. I also have QGIS 2.18.24 installed, the plugins are fully available there. Any idea what the issue might be?

EDIT:

I also tested with OSGeo4W Network Installer (64 bit), with the same result. Also note that grassplugin7.dll, grassprovider7.dll and grassrasterprovider7.dll are available in the folder C:OSGeo4W64appsqgisplugins

Here are my MSVC++ Versions

Ok, this is slightly embarrassing but I'll post the answer here anyway in case someone is as blind as I was. Apparently, there are two QGIS executable files: C:OSGeo4W64binqgis-bin.exe and C:OSGeo4W64binqgis-bin-g7.4.1.exe. In Windows, when firing up a program via the Windwos startup button, it runs qgis-bin.exe by default and GRASS does not work. When you run qgis-bin-g7.4.1.exe however, it GRASS works.

I'll show myself out

It looks like a faulty installation. I faced some plugin issue with OSGeo4W installation in windows OS whereas my Linux system is all good.

If there is not any specific reason to stick with 3.2.2, I would suggest to download and install the standalone version of QGIS 3.2.3-Bonn with GRASS 7.4.1.

Its running all fine in my Windows 10.
