安装配置JDK出错

转载自：https://blog.youkuaiyun.com/lsccsdn/article/details/52872652

命令行运行java -version 出现Registry key ‘Software\JavaSoft\Java Runtime Environment\CurrentVersion’
has value ‘1.8’, but ‘1.7’ is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.

解决方法：配置好了Path和ClassPath环境变量。
将 C:\Windows\System32和SysWOW64目录中的java.exe文件删除。
