用注册机来破解是成功的，但是下一次重启的时候就不可以了，是因为他登陆了官方网站去验证的原因，所以我们来屏蔽它的验证网站，就可以达到破解了。
无论是新安装的，还是试用期过期了的，我们首先在%SystemRoot%\system32\drivers\etc目录下的hosts文件进行修改在文件里面增加上127.0.0.1  activate.adobe.com这句话，如果提示不能修改，可能需要去掉只读属性后才可以修改。

如我的文件修改之后的内容：
# copyright (c) 1993-1999 microsoft corp.
#
# this is a sample hosts file used by microsoft tcp/ip for windows.
#
# this file contains the mappings of ip addresses to host names. each
# entry should be kept on an individual line. the ip address should
# be placed in the first column followed by the corresponding host name.
# the ip address and the host name should be separated by at least one
# space.
#
# additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a ‘#’ symbol.
#
# for example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
127.0.0.1     activate.adobe.com

修改完之后我们就可以进行注册了，如果有注册机的话，就可以很容易获取序列号了，如果没有的话在网上找也可以找到很多，在这里我提供一些吧，不知道能不能用，应该是可以用的，
