I have a problem working with ArcGIS. Sometimes (not always) when I run a geprocessing tool, I immediately get the pop-up with "completed" and a green tickmark. However, there is no output created, and it not realistic that the processing should finish so quickly.
I have not been able to discover a system as to when the tools work and when they do not. I have also tried with shorter names and putting them in locations with no spaces in the path string.
An example of a tool that does not work is Resample, but I also have problems with other tools.
