Spatial Analyst keeps crashing...

[JamesSnider]

I have been using Spatial Analyst with my version of ArcInfo Desktop (9.3) routinely on my workstation for more than a year until recently, and now everytime I attempt geoprocessing using the Spatial Analyst Toolbox, in ArcMap, ArcCatalog or using Python, my ArcGIS now crashes. According to my Desktop Administrator the Spatial Analyst extension is available. I have even tried changing licence keys, but still it continues to crash.

Is there a process I can follow to determine whether or not the extension is actually being accessed correctly? Or, barring that, does anyone have a suggestion (hopefully beyond reinstalling 9.3)?

Many thanks,
James

I have just reinstalled ArcInfo 9.3 and this problem with Spatial Analyst continues...

Anyone have a suggestion to what might be the problem?

Thanks,
James

I had similar issue previously. When I increased my RAM this issue was solved

Thanks Uday. Unfortunately, I don't believe it is a RAM issue, as there is 3GB installed and this problem occurs with all Spatial Analyst processing, including with small datasets and simple tasks.

I appreciate your suggestion, though.

Cheers,
James
