Longtime GIS'er but newbie to GRASS. I've never been able to get it to work properly on my workstation and have always fallen back on Esri or, QGIS built-in functions. Now I am in a situation where I have to get GRASS to work because it seems like the fastest way to do some hydro things. I am trying to use it inside of QGIS 3.12.
Here is my problem. I have a UTM-projected DEM as input, I just want to run r.flow and it fails, reporting:
"The following layers were not correctly generated. C:/Users/username/AppData/Local/Temp/1/processing_ipancU/89aab5fc64c6999046d99c2e0028b/flowaccumulation.tif C:/Users/username/AppData/Local/Temp/1/processing_ipancU/bded4092193446b883446b88344c55272310fa8/flowlength.tif C:/Users/username/AppData/Local/Temp/1/processing_ipancU/f4a65331b4ef4fa5a6b2ba826efdd9b4/flowline.gpkg
You can check the 'Log Messages Panel' in QGIS main window to find more information about the execution of the algorithm."
However, when I check the log messages panel, here is what I see:
Grass7 tab: only INFO level messages showing the original command payload
all the other tabs: nothing
So, not much given to troubleshoot. This behavior happens with *every* GRASS tool I try to run, including even v.buffer. So something is definitely not right.
*About my setup*
I do not have admin access rights to my workstation as this is a production box in a big enterprise. However I do have access to write to C:/ directories outside of the typical locked down stuff (Program Files, Program Files (x86), etc). I have QGIS currently installed to C:\QGIS_3 and GRASS sits under that. The workstation is not connected to the internet in case that matters.

some more details are needed:
* which GRASS GIS version used
* g.proj -p output
* g.region -p output
* exact command failing
I guess it has nothing to do with windows 10. works here on several windows
10 boxes.
Thank you Helmut - can you tell me how I run those commands at command line in OSGEO shell?
Also the folder says Grass78
Thanks,
eric
