Bug report #16429

Updated by Borys Jurgiel about 4 years ago

On Windows systems, the Processing configuration stores paths to GRASS/MSYS and R, which become invalid after upgrading QGIS to a newer version (they point to C:\\Program Files\\$QGIS_Older_Version\\foo when using the standalone installer on windows). As a result, you can't close the Processing Options dialog without updating those paths. However, 99% of the users don't even know what GRASS and R is, so they are surprised by the invalid path error. On most trainings I have to tell people to set the affected paths to C:\\ (or other dummy but existing location), what is a bit embarassing...



What about skipping the path validation if the relevant provider is disabled? It's better to tell users to disable unused providers rather than set dummy paths.
