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。 然而，每当自动更新尝试在应用程序启动之前安装更新时，安装程序都会进入一个无限循环，在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，启动程序仍会再次重新启动自动更新程序。 这是否意味着 install4j 安装的当前应用程序版本来自 Registry。有没有可能改变这个？
@英戈， 我已启用日志。 PFB 自动更新程序的日志：

cleaning up
Finished
我在 bgupdater 执行后检查了 i4jparams.conf 文件。 “sys.version”代表的版本仍然指向旧版本。
解决方法
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是在不同的位置安装应用程序，因为在更新期间有额外的指令来使用 context.setInstalltionDirectory 设置安装目录。
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。
