重新下载了stata16（把����Բ这个文件夹都删了）还是不行，并且plus文件夹的保存路径还在这个文件夹里（不知道和这个有没有关）
sysdir
   STATA:  C:\Program Files\Stata16\
    BASE:  C:\Program Files\Stata16\ado\base\
    SITE:  C:\Program Files\Stata16\ado\site\
    PLUS:  C:\Users\����Բ\ado\plus\
PERSONAL:  C:\Users\����Բ\ado\personal\
OLDPLACE:  c:\ado\
. ssc install diff
checking diff consistency and verifying not already installed...
cannot write in directory C:\Users\����Բ\ado\plus\d
r(603);

改了路径也不行
. ssc install diff
checking diff consistency and verifying not already installed...
cannot write in directory  C:\Program Files\Stata16\ado\plus\d
r(603);
请问大家有遇到这个情况的吗？怎么解决呀？
