我想要安装csdid命令，输入ssc install csdid，显示all files already exist and are up to date.  但是却无法正常使用csdid，会提示command csdid is unrecognized。之前安装其他命令时没有遇到过这样的问题。实在不知道怎么办了，恳请各位前辈不吝赐教。
我的具体操作如下：

----这第一步是因为我在csdn上看到有博主说，如果改变了stata的默认安装位置，可能会导致命令安装失败，因此我按照其教程将路径都更改过了，与软件安装位置统一。
【使用命令】
sysdir set PLUS "D:\Software\Stata16\ado\plus"
sysdir set PERSONAL "D:\Software\Stata16\ado\personal"
sysdir set OLDPLACE "D:\Software\Stata16\ado\oldplace"
sysdir
【显示如下】
. sysdir
STATA: D:\Software\Stata16\
BASE: D:\Software\Stata16\ado\base\
SITE: D:\Software\Stata16\ado\site\
PLUS: D:\Software\Stata16\ado\plus\
PERSONAL: D:\Software\Stata16\ado\personal\
OLDPLACE: D:\Software\Stata16\ado\oldplace\
【显示安装成功，但是csdid无法使用，显示如下】
