    • A method and computer-readable medium for upgrading an application program, and making an installer program aware that an application has been upgraded is disclosed. The method recognizes that an upgrade to the application has been initiated. The upgrade includes an identifier for the application to be upgraded, as well as information required for the installer to perform the upgrade. The installer program accesses the upgrade information, which includes instructions necessary for installing the upgrade. The installer program also accesses information related to the installed state of the application and related applications. The installer program determines whether or not the upgrade should be performed. If the upgrade should be performed, the installer program performs the upgrade and stores the fact that the application has been upgraded. If the application should not be upgraded, the installer program stores information reflecting the fact that the upgrade is available but not installed.
    • 公开了一种升级应用程序的方法和计算机可读介质,并且使安装程序意识到应用已被升级。 该方法认识到已启动对应用程序的升级。 升级包括要升级的应用程序的标识符以及安装程序执行升级所需的信息。 安装程序访问升级信息,其中包括安装升级所需的说明。 安装程序还访问与应用程序的安装状态和相关应用程序相关的信息。 安装程序确定是否应执行升级。 如果升级应该执行,安装程序执行升级,并存储应用程序升级的事实。 如果应用程序不能升级,则安装程序将存储反映升级可用但未安装的信息。

    • A system, method and computer-readable medium for creating patch rollback scripts for operations performed by an installer program module. A patch rollback script may be used to reverse an action of an installer program module so that a user's machine is restored to its original state, i.e., the state before the installer program module began performing patch operations. In performing patch operations, the installer program module typically generates patch installation script records of specific actions that are to be performed to a particular machine with regard to patch installation data. During the processing of each patch installation script record, an inverse record is created, known as a patch rollback script record. When installing or modifying a file, if there is no file with the same name in the same location stored on the machine, a patch rollback script record describing how to delete the file is stored. However, if an old file stored in the same location does exist, the old file is backed up to another location and a patch rollback script record is saved describing how to copy the old file back to its prior location on the machine.
    • 一种用于为安装程序模块执行的操作创建补丁回滚脚本的系统,方法和计算机可读介质。 可以使用补丁回滚脚本来反转安装程序模块的动作,使得用户的机器恢复到其原始状态,即安装程序模块开始执行补丁操作之前的状态。 在执行补丁操作时,安装程​​序模块通常会针对补丁安装数据生成要对特定计算机执行的特定操作的修补程序安装脚本记录。 在处理每个补丁安装脚本记录期间,创建一个反向记录,称为补丁回滚脚本记录。 安装或修改文件时,如果机器上存储的相同位置中没有相同名称的文件,则会存储描述如何删除文件的修补程序回滚脚本记录。 但是,如果存储在同一位置的旧文件存在,则将旧文件备份到另一位置,并保存修补程序回滚脚本记录,描述如何将旧文件复制回其在计算机上的先前位置。
