win7下安装Datastage 8.5检查环境报错
由于实习需要，要安装IBM的 Datastage 8.5 的客户端，在安装的过程中对系统所需环境检查报错：“microsoft windows script engine必须工作正常”。当时以为是script引擎的问题下了scripten来安装，还是不行。由于其他同事用的都是XP，只有我的是win7 64 bit我觉得是系统问题，但是我不怎么甘心放弃win7，就在我的另外一台台式机安装，结果居然可以。我顿时郁闷死。在网上找了好多方案都行不通，结果在一个老兄的博客找到跟我一样的情况，但是要加他为好友才能看blog ，在他加我为好友前，我继续我的悲剧人生……卸载……重装……卸载……一直折腾了好几天，然后忽然想起这事，没想到老兄居然加我了，我泪奔……PS：因为楼主加别人为好友的时候总是被忽略- -。于是我果断按照上面的方法做了，结果问题解决了，我十二万分的感激这位老兄，下面就是他的方法，我忘了他的网站，只是把当时的解决方案复制了下来，我只截取关键的解决方案，因为口水实在是有点……
google了一下那个错误，有人也遇到过，就是没人解答。我都有点心灰意冷了。记起来讲师说可以到ibm的surport去找支持。我就发了个email。估计这会还没回。然后就上ibm的inforspere网站去搜了一下错误。结果居然有Information Server 8.5 Client install fails checking system requirements for Windows Scripting Engine。链接地址：https://www-304.ibm.com/support/docview.wss?uid=swg21454181 。我建议win7下绝对不要reinstall the Microsoft Windows scripting。到目前为止我都没装上，还被微软给忽悠的乱删文件，后果很严重。
其实那个链接里的第一个方法就能解决。
主要对操作系统做了两处调整：
1、注册微软的jscript.dll。在命令行输入命令：regsvr32 %systemroot%\system32\jscript.dll
2、修正js的注册信息。就是导入一个注册表文件。大家把下面这段文本保存为xx.reg即可，名字随意。

重新检查应该就能通过了，接着就能顺利安装了。在安装的过程中貌似有一个选项是保存安装信息的，我每次都选择了，但是重复在同一个路径下安装时就会有问题，所以大家在安装的时候尽量选择不同的路径，我也不确定这是否跟这个选项有关
