安装RSLINX CLASSIC 是错误处理方法  

最近在安装RSLINX CLASSIC 2.57时，总是装不上，提示“Could not set RSICOMPANYDIRID identifier - Installation Failure # 14”，百度了半天也没有解决，最后终于找到一个解决方法，并按其描述成功安装了该软件

Cause: Missing information in the Windows Registery.
Solution: Enter the Windows Registry and locate the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Rockwell Software\Setup\Default\Common
Check the following values. They should look as follows, so correct them if necessary:
Name Type Data
Company REG_EXPAND_SZ C:\Program Files\Rockwell Software
SharedSystem REG_EXPAND_SZ C:\Program Files\Rockwell Software\RSCommon

If the Windows Registry appears correct, then verify the "path" variable in the Windows 'Environment Variables' includes the following:
C:\Program Files\Rockwell Software\RSCommon

简单概括就是

1、首先检查注册表是否有上面描述的信息，如果没有就按照描述的信心在注册表里建立这些值

2、在命令窗口下（cmd),然后输入set path=C:\Program Files\Rockwell Software\RSCommon ,然后正常安装该软件就可以了
