问题：每次打开PSCS5的时候都会提示需要输入序列号才能使用，有时候还要输入几次才可以使用。相信有不少人应该也遇见过这样的问题，下面我来说下我的解决办法
解决办法：其实就是通过系统的HOST表来屏蔽一些网站，让PS CS5不能自动更新就可以了 不影响其他功能的正常使用。
1，打开系统下的C盘下的这个目录：C:windows system32 drivers etc里面有一个HOST的文件
2，在桌面上建一个txt文本文档，直接把HOST文件拖入到刚简历的TXT文档里面，就可以看见HOST文件里面的内容
一般正常的内容如下：
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP forWindows.
#
# This file contains the mappings of IP addresses to host names.Each
# entry should be kept on an individual line. The IP addressshould
# be placed in the first column followed by the corresponding hostname.
# The IP address and the host name should be separated by at leastone
# space.
#
# Additionally, comments (such as these) may be inserted onindividual
# lines or following the machine name denoted by a '#'symbol.
#
# For example:
#
#102.54.94.97rhino.acme.com# source server
#38.25.63.10x.acme.com# x client host
127.0.0.1localhost
3，在上面正常文件的后面添加一下网址：
127.0.0.1activate.adobe.com
127.0.0.1practivate.adobe.com
127.0.0.1ereg.adobe.com
127.0.0.1activate.wip3.adobe.com
127.0.0.1wip3.adobe.com
127.0.0.13dns-3.adobe.com
127.0.0.13dns-2.adobe.com
127.0.0.1adobe-dns.adobe.com
127.0.0.1adobe-dns-2.adobe.com
127.0.0.1adobe-dns-3.adobe.com
127.0.0.1ereg.wip3.adobe.com
127.0.0.1activate-sea.adobe.com
127.0.0.1wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com
添加完成以后HOST内容：
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP forWindows.
#
# This file contains the mappings of IP addresses to host names.Each
# entry should be kept on an individual line. The IP addressshould
# be placed in the first column followed by the corresponding hostname.
# The IP address and the host name should be separated by at leastone
# space.
#
# Additionally, comments (such as these) may be inserted onindividual
# lines or following the machine name denoted by a '#'symbol.
#
# For example:
#
#102.54.94.97rhino.acme.com# source server
#38.25.63.10x.acme.com# x client host
127.0.0.1localhost
127.0.0.1activate.adobe.com
127.0.0.1practivate.adobe.com
127.0.0.1ereg.adobe.com
127.0.0.1activate.wip3.adobe.com
127.0.0.1wip3.adobe.com
127.0.0.13dns-3.adobe.com
127.0.0.13dns-2.adobe.com
127.0.0.1adobe-dns.adobe.com
127.0.0.1adobe-dns-2.adobe.com
127.0.0.1adobe-dns-3.adobe.com
127.0.0.1ereg.wip3.adobe.com
127.0.0.1activate-sea.adobe.com
127.0.0.1wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com
添加完成以后，直接保存txt文本文档，这样HOST文件就编辑完成了。
4，在重新打开PS CS5文件，这时还会提示输入序列号，您使用自己的PSCS5注册机生成序列号输入就可以了，在下次打开就不会提示了。
下面提供几个序列号：
1325-1558-5864-4422-1094-1126
1325-1958-5864-4422-1094-1178
1330-1927-7762-6383-0202-0414
1330-1646-9096-8797-0840-3597
