    • Systems and methods are provided for auditing and selectively restricting software usage based on, for example, software copy counts or execution counts. In one embodiment, the method comprises verifying whether the serial number for a software installed on a computing device corresponds to one of recognized serial numbers, and calculating a copy count (or software execution count) for the serial number. In response to the copy count exceeding a defined upper limit, a limited unlock key may be sent to the device. The limited unlock key may allow the software to be executed on the device for a defined time period, a defined number of executions, and/or with at least one feature of the software disabled.
    • 提供了系统和方法,用于根据例如软件复制计数或执行计数来审核和选择性地限制软件使用。 在一个实施例中,该方法包括验证安装在计算设备上的软件的序列号是否对应于识别的序列号之一,以及计算序列号的复制计数(或软件执行计数)。 响应于超过限定的上限的复印次数,可以向设备发送有限的解锁密钥。 有限的解锁密钥可以允许软件在设备上执行定义的时间段,定义的执行次数和/或软件的至少一个特征被禁用。

    • An installation image for installing an unprotected software product is used to install a protected version of the same product. A protected version of the executable file is embedded in a new installation image with the original installation image, in which the unprotected version of the executable file is damaged so as to be unusable and unreadable. The new installation image causes the original installation image to operate, installing the damaged installation file and other data files. The new installation image then replaces the damaged installation file with the protected installation file.
    • 用于安装不受保护的软件产品的安装映像用于安装同一产品的受保护版本。 可执行文件的受保护版本嵌入到具有原始安装映像的新安装映像中,其中未受保护的可执行文件的版本被损坏,以便不可用和不可读。 新的安装映像使原始安装映像运行,安装损坏的安装文件和其他数据文件。 新的安装映像然后用受保护的安装文件替换损坏的安装文件。
