The Geographic Weighted Tool in 10.1 cannot write out a raster coefficient files. Everything else works. Error is the infamous ???ERROR 999998: Unexpected Error???. It can???t create output raster. It completes the first coefficient file, but the program crashes about 20% into the second coefficient file and deletes all files. I was able to examine the first file once before it crashed. It did not have any useful data or use use the environment settings. Has anyone made it work?
