java - Install4j 安装程序在出现 NullPointerException 的第一个欢迎屏幕之前停止

Question

我们有一个 install4j 安装程序，该安装程序在“正在准备 install4j 向导”阶段结束时和“欢迎使用...安装向导”屏幕之前停止。两个客户(数千个)都发生过这种情况，他们都运行 Windows 7。以前从未发生过这种情况，而且我们已经使用 install4j 多年了。安装程序不会挂起 - 您可以取消它。它就停止了。我们从其中一个日志文件中得到以下信息。我们已经寄出了经过检查的替换CD等。我们尝试过“以管理员身份运行”。有什么想法可能导致这种情况吗？

Answer 1

这很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，如果他们将外观重置为默认值，应该可以解决问题。
