你不会那种安装，那就安装stata官方主页的提醒安装


Extract the file you downloaded to a temporary location on your system.
After you have extracted it, you will have one of the following directories on your system with several files in it:

stata12update_win64		stata12update_linux64
stata12update_win32		stata12update_linux32
stata12update_mac		stata12update_solaris

Type db update in Stata and browse to the extracted update directory. Click OK and follow any instructions you are given.
After installing the updates, you can remove the downloaded update file and files you extracted from it.

我就按照这个步骤弄的，可是出现提示说bad serial number
我要疯了

我又试了一次，这回升级成功了。多谢你的帮助。
不过我现在我做面板分析是，输入xtoverid命令后，提示说：
Error - must have ivreg2/ivreg29/ivreg28 version 2.1.15 or greater installed
这是怎么回事？
