Just replace the 3D fotocube.exe in the program folder with this one.

After installation just replace the two files with the ones that I have provided.  Instead of cracks I have given the actual files themselves.

This program can be downloaded from

ftp://ftp.zdnet.nis.newscorp.com/pub/private/sWlIB/graphics_fonts_multimedia_files/video_animation/3dfotc.zip
 
3-D Fotocube is a screen saver that takes up to six of your favorite BMP or JPEG files and puts them on the side of a
spinning, three-dimensional cube against a twinkling star field. You can also option to have a smaller "spinner"
satelite orbiting around the larger cube.  Anything that you can save in BMP or JPEG format can be placed on the cube
including photos, clip art, logos, and text. Customize display quality and speed to match your tastes and system
capabilities.
 
The trial version of the screen saver has a one minute time limitation on each consecutive picture  in that after one
minute one of the sides of the cube becomes a brick wall instead of the picture you put on it.  After another minute
another picture becomes a wall and so forth until all 6 sides are just ugly walls instead of pictures.  Everything else
about the program works as a full version, just the dissapearing pictures.

I used a hex editor and information provided by BiteMyLeg to change this into the full version.  All credit goes to BiteMyLeg for this one, and I am glad to give it!  I just want to thank him for the info on which values to change.  I fully admit that I could not have done this on my own at all.  Thanks BML!
