你好 我这边还是安装不上呢,一直报错
. est restore first
estimation result first not found
r(111);
昨天捣鼓完了之后first可以了,second又不行了,今天重新运行命令first又报错了==
请问是怎么回事呢,下面是我安装时的提示
package name: st0030_3.pkg
from:
http://www.stata-journal.com/software/sj7-4/
checking st0030_3 consistency and verifying not already installed...
the following files already exist and are different:
c:\ado\plus\i\ivreg2.ado
no files installed or copied
Possible things to do:
1. Forget it
(best choice if any of the above files were written by you and just
happen to have the same name or you do not want the originals changed)
2. Look for an already-installed package of the same name
(which you might then choose to uninstall)
3. Search installed packages for the duplicate file(s) by clicking
on the file names above
4. Force installation replacing already-installed files
(if this is an update, this would be a safe choice; you will end
up with the original and the update apparently installed, but it
doesn't matter; you can even uninstall the original later)
(no action taken)

求大佬们指点
