問題：每次打開PSCS5的時候都會提示需要輸入序列號才能使用，有時候還要輸入幾次才可以使用。相信有不少人應該也遇見過這樣的問題，下面我來說下我的解決辦法

解決辦法：其實就是通過系統的HOST表來屏蔽一些網站，讓PS CS5不能自動更新就可以了 不影響其他功能的正常使用。

1，打開系統下的C盤下的這個目錄：C:windows system32 drivers etc里面有一個HOST的文件

2，在桌面上建一個txt文本文檔，直接把HOST文件拖入到剛簡歷的TXT文檔里面，就可以看見HOST文件里面的內容

一般正常的內容如下：

# 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網址：

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內容：

# 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文本文檔，這樣HOST文件就編輯完成了。

4，在重新打開PS CS5文件，這時還會提示輸入序列號，您使用自己的PSCS5注冊機生成序列號輸入就可以了，在下次打開就不會提示了。

下面提供幾個序列號：

1325-1558-5864-4422-1094-1126
1325-1958-5864-4422-1094-1178
1330-1927-7762-6383-0202-0414

1330-1646-9096-8797-0840-3597
