MyEclipse6.5 GEN (zt)

新装的MyEclipse6.5在网上找了半天的注册码，都不可用。将下面的代码放在MyEclipse下运行后，可以得到注册码。这相当于一个注册机。我得到的如下：

administrator

nLR8ZC-855550-60675256396752354

断网粘贴上去之后：

Subscriber: administrator
Product ID: E3MP (MyEclipse Professional Subscription)
License version: 3.0
Full Maintenance Included
Subscription expiration date (YYYYMMDD): 20151207
Number of licenses: 5

可以用到2015年!真的不错!
