Hi there! Let me tell you my story about this issue. I read many and many threads and advices but nothing helped me. I take the message "invalid raster dataset. failed to create raster layer" probably a million times. I've reinstalled my OS and changed it from Win7 Professional SP1 to Win7 Ultimate but this give me no result. I am student and a part of my exercises was to create this layer anyway. Another part of the exercises was to create raster from point feature with interpolation tools /Kriging method/. So I create the layer but choose my output raster to be in a default geo database created from the software itself. This was easy job and i have no problems. Few weeks after that I decide to try again to load the raster but I decide to load it in the default geo database where was my kriging output surface layer. AND IT WORKS... ... my explanation is that the software creates some files that are needed for loading the rasters and ones it create it there are no problems with loading raster layer anywhere you choose. Hope this will help for anyone. Please excuse me for my bad English
