问题描述

我下载了 JDK8 build b121 并且在尝试安装时出现以下错误:

I downloaded JDK8 build b121 and while trying to install I'm getting the following error:

在动态链接库ADVAPI32.dll中找不到过程入口点RegDeleteKeyExA

操作系统为 Windows XP，版本 2002 Service Pack 3，32 位.

The operating system is Windows XP, Version 2002 Service Pack 3, 32-bit.

推荐答案

发生这种情况是因为 Oracle 放弃了对 Windows XP 的支持(安装程序在其 ADVAPI32 中没有使用 RegDeleteKeyExA.DLL 顺便说一下)如 http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/009005.html.然而，虽然对 XP 的官方支持已经结束，但 Java 二进制文件仍然(至少从 Java 8u20 EA b05 开始)与 XP 兼容——只是安装程序不是......

This happens because Oracle dropped support for Windows XP (which doesn't have RegDeleteKeyExA used by the installer in its ADVAPI32.DLL by the way) as described in http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/009005.html. Yet while the official support for XP has ended, the Java binaries are still (as of Java 8u20 EA b05 at least) XP-compatible - only the installer isn't...

因此，解决方案实际上很简单:

Because of that, the solution is actually quite easy:

获取 7-Zip(或任何其他好的解包器)，手动解压发行版 .exe，其中包含一个 .zip 文件(tools.zip)，也将其解压缩,

使用 JDK8 中的 unpack200 将所有 .pack 文件解压为 .jar 文件(旧的解包将无法正常工作)；JAVA_HOME 环境变量应设置为您的 Java 解包根目录，例如"C:Program FilesJavajdk8" - 您可以通过例如

use unpack200 from JDK8 to unpack all .pack files to .jar files (older unpacks won't work properly); JAVA_HOME environment variable should be set to your Java unpack root, e.g. "C:Program FilesJavajdk8" - you can specify it implicitly by e.g.

SET JAVA_HOME=C:Program FilesJavajdk8

使用单个命令解压所有文件(在批处理文件中):
- Unpack all files with a single command (in batch file):
```
FOR /R %%f IN (*.pack) DO "%JAVA_HOME%inunpack200.exe" -r -v "%%f" "%%~pf%%~nf.jar"
```
- 使用单个命令(来自 JRE 根目录的命令行)解压所有文件:
- Unpack all files with a single command (command line from JRE root):
```
FOR /R %f IN (*.pack) DO "binunpack200.exe" -r -v "%f" "%~pf%~nf.jar"
```
- 通过手动定位文件并一一解压来解压:
- Unpack by manually locating the files and unpacking them one-by-one:
```
%JAVA_HOME%inunpack200 -r packname.pack packname.jar
```
