Hello,
I think there is a bug (please correct me if I am wrong) in ArcGIS 10.8. Every time I use the Reclassify and Extract by mask tool without changing the default output path (which is the default database that ArcGIS creates in the software installation directory), the tools work fine. But each time, when I change the output path and output filename, the tools return 9999 error. Is there a way to resolve this issue?
