install4j - 当前版本的应用程序存储在哪里？答案

【问题标题】：install4j - Where is the current version of application stored?install4j - 当前版本的应用程序存储在哪里？

【问题描述】：

我们的 RCP 应用程序使用 intall4j 进行安装。我们的客户要求我们安装程序不应将任何条目写入注册表。为此我们从安装步骤中删除了“注册添加/删除项目”操作。但是，每当自动更新尝试在应用程序启动之前安装更新时，安装程序就会进入无限循环，其中自动更新后更新再次被触发。我们认为这是因为自动更新安装程序尚未更新当前版本的应用程序，因此即使在更新后，启动器仍会再次重新启动自动更新程序。这是否意味着 install4j 安装的应用程序的当前版本来自 Registry。有可能改变吗？

@英戈，我已启用日志。 PFB 自动更新程序的日志：

我在 bgupdater 执行后检查了 i4jparams.conf 文件。 “sys.version”所代表的版本仍然指向旧版本。

【问题讨论】：

版本不在注册表中，而是在<installation directory>/.install4j/i4jparams.conf中。使用参数-Dinstall4j.log=<path to writable log file> 启动更新下载器，然后您会看到它为什么再次下载更新。
@IngoKegel，我已经更新了上面的日志。运行我的更新程序后，我可以看到 conf 文件中的版本仍然相同。
我还可以看到错误 "com.install4j.runtime.beans.actions.control.RunScriptAction [ID 1349]: no shutdown file property" 。我已经使用 'UpdateChecker.executeScheduledUpdate(Arrays.asList("-q", "-splash", "Updating ..."), true, null);'的脚本立即启动了 bgupdater
你确定下载的安装程序真的执行了吗？文件<installation directory>/.install4j/i4jpara,s.com 更新了吗？另外，下载的安装程序是普通安装程序而不是“附加”安装程序吗？
是的，我手动执行了 .install4j 文件夹中的 bgupdater.exe。不，参数文件根本没有更新。它是常规安装程序，而不是附加安装程序

标签： install4j auto-update

【解决方案1】：

我的安装程序本身的问题。在更新安装期间，更新安装程序实际上将应用程序安装在不同的位置，因为在更新期间有使用 context.setInstalltionDirectory 设置安装目录的附加说明。
因此，安装本身进入了无限循环。一旦我删除了这个不必要的步骤，问题就得到了纠正。谢谢。
