我正在尝试使用Eclipse进行Android开发。我在尝试运行Eclipse时遇到了这个问题，因为几分钟前刚刚安装了4.2版本。
在第一次尝试在没有任何参数指定Java VM的情况下启动Eclipse之后，我得到了一条错误消息，说它在Eclipse文件夹中找不到一个名为javaw.exe的Java VM，所以我找到了Java安装的位置，并在快捷方式的目标中将该位置指定为参数。现在我得到一个不同的错误，Java已经启动，但返回退出代码=13。
类似的问题似乎表明这是一个32位/64位的冲突，但我有99%的肯定，我下载了64位版本的Eclipse和Java (RE 7u5)，我选择这两个版本是因为我有64位的Windows 7。
如果有人知道如何确认我的Eclipse和Java是64位的，
非常感谢。
如果你认为我的问题不同，请帮忙!
请尽量直白地说，因为我对Eclipse完全不熟悉
和Java。

冒着不能给现有答案增加太多价值的风险，但我自己也经历过这些混乱，我想看看我是否能巩固我解决问题的方法:
Maintain separate Development from your normal machine environments. The reason for this is that there are probably many applications running on your machine that you are not aware of that need Java to be updated occasionally, for example banking and security applications. When those updates occur they change the environmental variables and so if you are using those in your development environment the update will almost certainly break your Eclipse setup.
Install versions of Eclipse, either 32 and 64 bit depending on your plugins etc. The reason is that many plugins still require 32bit and trying to install them into a 64bit environment causes many obscure (very obscure) errors. This means for example you may have to have separate instances of Eclipse for your Java EE, PHP, Python, Assembler, etc, development environments. This may appear to be onerous, but for me this has been a blessing.
Install two Java runtimes once again one 32bit and one 64bit and then edit the eclipse.ini for each of your installations to point to the correct JRE, not the JRE HOME in the environmental variables. I create a directory in C:\Java\64bit\jdk1.7.0_15\ and C:\Java\32bit\etc and in your eclipse.ini file you add the -vm C:\Java\64bit\jdk1.7.0_15\bin line to point to your needed java runtime.
一旦完成上述工作，您就可以随心所欲地安装Java sdk更新，但您的开发环境永远不会中断。如果您需要更新开发运行时环境，只需更改eclipse.ini中的-vm路径
请检查是否在“环境变量”部分设置了两个JAVA路径。如果你已经安装了两个版本的JDK，那么仔细检查你是否像下面这样为Java设置了PATH。
PATH --> C:\ProgramData\Oracle\Java\javapath
也
JAVA_HOME ---> C:\Program Files\Java\jdk1.7.0_02\bin
如果两者都存在，则可能发生这种错误。
如果没问题，然后在“。ini”文件中检查下面的区域是否OK。
打开“。ini”文件并检查
-VM path is C:\Program Files\Java\jdk1.7.0_79\bin\
如果不是，请将其设置为这样并重新运行。
