Systems and methods are provided for activation of software that uses digital licenses. In some embodiments, a software vendor may securely deliver at least one digital proof-of-purchase to an OEM (e.g., to avoid piracy of software licenses). The OEM may install an associated software copy on a computer system, and store the at least one digital proof-of-purchase on it. The OEM may communicate the proof(s)-of-purchase stored on the computer system and its system identifier to the software vendor. A user of the computer system may attempt to activate the OEM pre-installed software by sending an activation request to a software vendor, who may verify whether or not the digital proof-of-purchase and system identifier in the activation request match those previously reported by the OEM, and may either grant or deny the activation request.
