Hello Hena, maybe the libpng12.so.0 libraries on your system happen to be all 32-bit versions. You installed the 64-bit version (because of the "x86_64" in the name of the tar-archive), therefore you also require a 64-bit version of the libpng12.so.0. Do you have such a file in /usr/lib, and if so, is it really a file or maybe only a link to a file which once existed on your system?
