However, since the function *ExactCover* is loaded into a Mathematica session thanks to the command Needs["Imtek`ExactCover`"], we can infer that the code resides in its own package within a directory called "Imtek". So, after a successful installation, look for a directory called "Imtek". Within this directory, look for a file called "ExactCover.m" (the package) and possibly a file called "ExactCover.nb" (a notebook that is used to build the package). If you cannot find any of these files, that means that the IMS packages are not correctly installed or, at least, not fully installed. Regards, -- Jean-Marc
