Question

我们有一个install4j安装程序，它在“正在准备install4j向导”阶段结束时停止，就在“欢迎使用...安装向导”屏幕之前。这种情况发生在两个客户（成千上万）中，都运行Windows 7.它从未发生过，我们多年来一直在使用install4j。安装程序不会挂起 - 您可以取消它。它就停止了。我们从其中一个日志文件中获得了以下内容。我们已经发出了已经检查过的替换CD等。我们尝试过“以管理员身份运行”。关于可能导致这种情况的任何想法？

Answer 1

这可能是由客户计算机上的特定（自定义？）外观和感觉引起的。因此，如果他们将外观和感觉重置为默认值，则应该解决问题。

Answer 2

我有一个非常相似的堆栈跟踪，继上面ben75的回答后，在Install4J帮助中发现了以下内容（http://resources.ej-technologies.com/install4j/help/doc/index.html）

这解决了我在某些Windows 7和Windows 8系统上运行的安装程序的问题。
