If SAGA is not installed with osgeo4w then Processing has always allowed to use and external SAGA installation by configuring the proper path in Processing configurations.



While testing the support for SAGA LTR I therefore downloaded



https://downloads.sourceforge.net/project/saga-gis/SAGA%20-%202.3/SAGA%202.3.1/saga_2.3.1_x64.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fsaga-gis%2Ffiles%2FSAGA%2520-%25202.3%2FSAGA%25202.3.1%2F&ts=1491557320&use_mirror=netcologne



uncompressed and pointed Processing to it.



Processing correctly recognizes SAGA and SAGA version, tools open and are run, but ultimately they fail. This does not happen if used SAGA ltr is the one shipped with osgeo4w. This anyway used to work as expected in the past.
