我终于找到一个可行的解决方案。
您需要三样东西拉这一关:
- 的组件脚本,
- 目标目录页面自定义用户界面,并
- 通过卸载程序自动点击控制器脚本。
我现在要逐字列出对我有用的东西(用我的项目特定的东西)。我的组件被称为Atlas4500 Tuner
config.xml中:

packages/Atlas4500 Tuner /数据/脚本/ auto_uninstall.qs:
// Controller script to pass to the uninstaller to get it to run automatically.
// It's passed to the maintenance tool during installation if there is already an
// installation present with: <target dir>/maintenancetool.exe --script=<target dir>/scripts/auto_uninstall.qs.
// This is required so that the user doesn't have to see/deal with the uninstaller in the middle of
// an installation.
function Controller()
{
gui.clickButton(buttons.NextButton);
gui.clickButton(buttons.NextButton);
installer.uninstallationFinished.connect(this, this.uninstallationFinished);
}
Controller.prototype.uninstallationFinished = function()
{
gui.clickButton(buttons.NextButton);
}
Controller.prototype.FinishedPageCallback = function()
{
gui.clickButton(buttons.FinishButton);
}
这里的想法是,以检测如果当前目录中有一个安装与否,而且,如果这样做,运行在该目录中的维护工具与控制器只需点击它的脚本。
请注意,我将控制器脚本放在作为实际组件数据一部分的脚本目录中。如果你有多个组件,你可以做更干净的事情,但这是我正在使用的。
你应该可以为自己复制这些文件,只需调整字符串使其工作。
这让我走上了正确的道路,因为维护工具的运行就像这样。但是,“RemoveTargerDir”不会执行任何操作。看到我的答案为我提出的解决方案。 – rationalcoder
