izPack创建一个卸载程序，该卸载程序无法在Windows的“程序和功能"(Windows)中运行. [英] izPack creates an uninstaller that doesn't work in Windows "Programs and Features"

问题描述

我正在使用izPack 4.3.4为Java项目开发图形安装程序，安装进行得很好，但是当我尝试通过在程序和功能"窗口中单击他的引用来尝试卸载它时，该消息将显示消息:/p>

I'm working on a graphic installer for a java project using izPack 4.3.4, the installation goes well but when I try to uninstall it by clicking on his reference in "Programs and Features" window it shows the message:

Error: Unable to access jarfile C:\Program Files (x86)\myproject\uninstaller\uninstaller.jar

事实是，我选择在程序的根安装路径中而不是\ uninstaller目录中放置并重命名卸载程序.参见XML:

The fact is that I choosed to put and rename the uninstaller in the root install path of my program and not in \uninstaller dir. See the XML:

<info>
...
  <uninstaller name="uninstall.jar" write="yes" path="${INSTALL_PATH}" />
...
</info>

而且，实际上，在C:\ Program Files(x86)\ myproject \中创建了uninstall.jar文件，如果我双击它或在开始"菜单中双击它，它将起作用.我认为izpacks在Windows注册表中写入了错误的数据，以在程序和功能"中对其进行引用...但是我不知道为什么...

And, in fact, uninstall.jar file is created in C:\Program Files (x86)\myproject\ and it works if I double click on it or throught the Start Menu. I think izpacks writes the wrong data in the Windows's registry to reference it in "Programs and Features"... but I don't know why...

推荐答案

如果要在Windows上使用IZPack进行安装，则可以(应该)拥有RegistrySpec.xml.那个人会写出您需要的所有注册表项. Windows查找注册表值"UninstallString"作为要启动卸载的文件，您可能需要覆盖该值.例如我的:

If you're installing using IZPack on Windows, you can (should) have a RegistrySpec.xml. That guy writes all the registry entries you need. Windows looks for a Registry Value "UninstallString" as the file to run to kick off your uninstall, and you likely need to overwrite that. For example on mine:

<pack name="UninstallStuff">
<!-- Special "pack", if not defined an uninstall key will be generated automatically -->
<value name="UninstallString"
    keypath="SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$APP_NAME"
    root="HKLM"
    string="$INSTALL_PATH\uninstall\uninstaller.cmd"/>    
<pack name="UninstallStuff">
