I don't know why you're having trouble with the processing toolbox, but regarding IDW interpolation, you can do it straight in the Raster menu, Raster->Analysis->Grid (interpolation). This uses the gdal_grid utility

Hi

I need to use the Inverse Distance Weighted Interpolation from SAGA within qGIS, which I did with a previous version of qGIs but this time it didn't work because of a missing library (qGIS 2.18.9 - windows8 pro, 64bits).

I updated the qGIS version with the latest 2.18.10 (windows8 pro, 64 bits), but this time the SAGA tools are not displayed at all in the list, despite they are ticked in the config file.
Is this normal? What is then the workaround for the IDW interpolation?

Also the path to grass7 in the config file is wrong (processing / options), which makes it crash ... Is this also normal?

Thanks for the help in advance!
