Hello,
i am having an issue with Geostatistical Analyst not respecting my environmental variables. i have set the TMP and TEMP system and user vars to my desired folder and have pointed to the same location in the Advanced Arc Map settings. and rebooted the machine.
When i load my data into the wizard and select next i can see my c:\ drive decrease in size while the data is loading (presumable the c:\ is being used as the temp space) and the the desired d:\tmp folder does not grow in size.
Running ArcGIS for desktop 10.1 sp1 on a windows server box.
