I do not have the IMS package installed on the machine I am working.
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

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.
