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。这发生在两个客户（数千名）中，他们都运行 Windows 7。以前从未发生过这种情况，我们已经使用 install4j 多年了。安装程序不会挂起 - 您可以取消它。它只是停止。我们从其中一个日志文件中得到以下信息。我们已经发送了经过检查的替换 CD 等。我们尝试了“以管理员身份运行”。关于可能导致这种情况的任何想法？

这很可能是由客户计算机上的特定（自定义？）外观引起的。因此，如果他们将外观重置为默认值，它应该可以解决问题。

我有一个非常相似的堆栈跟踪，并根据上面 ben75 的答案在 Install4J 帮助（http://resources.ej-technologies.com/install4j/help/doc/index.html）中找到以下内容

-Dinstall4j.nolaf=true

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。
