Did you get a reply to this question? I am having the same problem.. Hello, I'm attempting to multiply one grid by another in the Raster Calculator. I'm running ArcGIS 10 on a Windows 7 machine. Both grids have the same spatial reference, cover the same extent and the cells line up. I've set the SnapRaster, cell size and processing extent environmental settings. I cannot see any reason why this isn't working. I get ERROR 000539: Error running expression: rcexec() & ERROR 00732: Input raster Dataset ....does not exist or is not supported. Any ideas would be greatly appreciated. Kurt Menke
