Question

我们为次要升级安装程序升级到最新的JRE / install4j，当我们尝试使用install4j API时，我们开始收到以下错误：

2017-02-17 19:29:42 SEVERE:  #{14} [StandardContext.loadOnStartup] Servlet [ConfigServlet] in web application [] threw load() exception
java.lang.UnsatisfiedLinkError: com.install4j.runtime.installer.platform.win32.Common.setWindows95(Z)V

我们尝试启动卸载程序时遇到同样的错误：

造成这种情况的原因是什么？

Answer 1

API JAR文件（i4jruntime.jar）与本机库（i4jinst.dll）不匹配。您的类路径中似乎有旧版本的i4jruntime.jar。

使用install4j 6.1.4和JRE 1.8.0_121获取java.lang.UnsatisfiedLinkError
