[python]there is a problem with widows installer package,a program run as part of setup did not finish as excepted. contact your support personel or package vendor

之前电脑上有python2.7.9，因tribon程序需要装了2.3.3，结果卸载2.7.9时提示there is a problem with widows installer package,a program run as part of setup did not finish as excepted. contact your support personel or package vendor. 现已强制卸载，但是再次安装python2.7.9时还是提示这个错误，请问有什么解决办法吗？系统是win7 64位

解决办法：

安装时选择for me，不是for all users ，（我也没选择安装pip），我的已经成功安装。
