我需要从安装的64位java 7切换到我的Windows 7 64位操作系统上安装的java 6,但通常的步骤不起作用。

推荐答案
您还需要切换路径环境变量,指向JRE之前bin目录。另外,我认为现代版本的java在Windows的system32目录中放置了java.exe的副本,你需要将它们删除(或者如果你想将它们作为备份重命名它们)。
You need to switch the path environment variable too, to point before to the JRE bin directory. Also, I think modern versions of java place a copy of "java.exe" in the system32 directory of Windows, you'll need to remove them (or rename them, if you want to keep them as backups).
