I'm experiencing an error when trying to run a heatmap in QGIS. I just downloaded QGIS 2.18.10 'Las Palmas' on my Windows 10 Laptop as the 64 bit option.
I am hoping to run some very simple heatmaps, following the instructions laid out here: http://www.qgistutorials.com/en/docs/creating_heatmaps.html.
I was able to follow those steps without issues when I used this in the past, but this time I get stuck after step 10 (converting the delimited text layer which I had imported from a CSV file to create the raster layer). When I follow the steps to add this layer, I receive the error "Raster update error: Could not open the created raster for updating. The heatmap was not generated."
My heatmap plugin came already installed, and I don't have the option to uninstall/reinstall it. Also I have already attempted to restart the program as the previous user had done.
Does anyone have suggestions as to what may have gone wrong, or what I should do differently?
Alternate instructions for creating a heatmap (to later layer over a world map and/or street view)?
