After the regression,using the "outreg varlist,options[command]'command ,then the outcome will be got in the format with word (rtf).but first of all, you should install the ado by using "ssc install outreg"

您好，我输入后结果如下：
. ssc install outreg
checking outreg consistency and verifying not already installed...
installing into c:\ado\plus\...
could not rename c:\ado\plus\stata.trk to c:\ado\plus\backup.trk
r(699);

请问该怎么安装呢，最近一直在找如何安装outreg，貌似都不work，急求。
