我已经构建了一个 NSIS，它已经运行了几个月， 突然JRE出现下载失败的问题，我已经测试了下载链接是好的，如果有人可以帮助，请提出可能的解决方案，部分代码如下所列：

!define JRE_URL "javadl.sun.com/webapps/download/AutoDL?BundleId=69476"
Function GetJRE
    MessageBox MB_OK "${PRODUCT_NAME} uses Java ${JRE_VERSION}, it will now \
                     be downloaded and installed"

    StrCpy $2 "$TEMP\Java Runtime Environment.exe"
    nsisdl::download /TIMEOUT=30000 ${JRE_URL} $2
    Pop $R0 ;Get the return value
            StrCmp $R0 "success" +3
            MessageBox MB_OK "Download failed: $R0"
            Quit
    ExecWait $2
    Delete $2

nsisDl 使用自定义 HTTP 库。请改用INetC，它使用与 Internet Explorer 相同的 HTTP 库。
