Trying the operation on a new blank map solved this issue for me. Thanks!

JimCousins

Your file processes fine. The trouble seems to reside in your configuration. Have you tried a blank map, adding in 1 raster, and running the process? If this fails, you could try resetting to original install configuration, or run a detect and repair on the software.
A link to a forum post on resetting configuration:

It runs fine for me with multiplying each of them. Can you indicate if you have any other python modules installed or if you have a different version of python that may have been installed? I would also consider putting a file extension such as .tif or .img to your output and see if that allows the process to complete.

JeffBoyd

I've attached the raster, in two versions. The one ending in 'I' is an integer raster, the one in 'F' is floating point. Neither one works for me in Raster Calculator.
thanks for your help.

Puzzling. Can you share your raster file?

JeffBoyd

Jim, yes, that is how I setup the calculation.
thanks,
Jeff

It all looks fine. No filenames too long (over 8 characters) or beginning with a number, no spaces in the file names or directory paths, no putting output into a geodatabase, so no permission issues. It should run. Attached is the setup I used in Raster Calculator.
How does it compare to your Raster Algebra setup?
Regards, Jim
