The systems and methods provided herein determine at least one first file system path related to a specific software package. A second file system path associated with a computing process running on the computer system is determined, and use of the specific software package on the computer system is detected based on comparing the first file system path with the second file system path. Thus, the present techniques determine the installation director(ies) of the application(s) and then compare active processes to determine whether an application is in use or is only installed.
