A method for performing software discovery by an installer controller is provided and may include detecting, at a computer, an attempt by a software installer to execute on the computer, wherein during execution, the software installer modifies software on the computer. A Software Asset Management (SAM) computer server may be queried for an approval status corresponding to a software package provided by the software installer. The installer controller executes the software installer upon receiving on the returned approval status; aggregates a result from the execution of the software installer based on the software installer modifying the software on the computer; and updates a discovery software signature on the computer when the returned approval status is marked as known.
