Question

如果Windows配置了＆＃34;代理脚本＆＃34;则install4j静默更新检查过程似乎挂起。那已经不存在了。例如：当它设置为http://127.0.0.1:50000/proxy.pac时，IE会给出＆＃34;连接拒绝错误＆＃34;，但是在尝试下载脚本时，install4j将无限期地等待。

这也会阻止我们自己的应用程序启动，因为它被配置为在静默更新检查后启动。

安装程序和更新程序是在Install4j 6.1.2中创建的。我没有在6.1.3的更改日志中看到任何可以解决此问题的内容。你能看看还是给我们一个解决方法？

Answer 1

该错误在JRE类中，因此我们无法直接修复它。唯一的选择是传递VM参数

-Dinstall4j.noProxyAutoDetect=true

到安装程序，以便关闭代理自动检测。

如果代理设置不正确，Install4j静默更新程序进程将挂起
