重装吧，先全部卸载

我重装了好几遍还是一样的问题啊

卸载完。主要包括：在添加和删除里面卸载完毕、在所有盘里面把带有sas字样的文件全部删除、把JAVA也要卸载掉。然后清理一下注册表和垃圾文件。重启再安装试试。

回收站也要清空。

我是按照下面的方法解决的。

First, correct the warning:
WARNING: One or more libraries specified in the concatenated library SASHELP do not exist.
   These libraries were removed from the concatenation.

  Navigate to the
sasroot\nls\en
folder and create a folder called SASCFG (if it does not already exist).  For
sasroot
,
use the installation path for SAS 9.3. The following sample paths
illustrate default 32-bit and x64 paths. Use the path that is applicable
to your system and your SAS installation.

Examples of Paths
C:\Program Files\SASHome\SASFoundation\9.3\nls\en

   C:\Program Files\SASHome\x86\SASFoundation\9.3\nls\en
  
Once you have created the SASCFG folder, the resulting path should
resemble one of these examples, depending on which one is applicable to
your system and SAS installation:
C:\Program Files\SASHome\SASFoundation\9.3\nls\en\SASCFG

   C:\Program Files\SASHome\x86\SASFoundation\9.3\nls\en\SASCFG

这个方法就是多增加文件夹是吧，这样我还是不行
