Matlab2012b licence失效解决办法

     刚过了2017年光棍节两天，寻思搞点科研吧，处理点数据。打开MATLAB，让我注册，心想这不是so easy，重新加载一下license就行了，结果加载完告诉我“注册成功！”。悲催的是打开.exe还是让我注册，无奈卸了重装还是没有解决。

       网上一搜，发现有哥们说license只到2017年11月11日，打开一看果不其然“INCREMENT Aerospace_Blockset MLM 2711-nov-2017 uncounted \0B090909C2B0F51094E VENDOR_STRING=VI=0:AT=186 HOSTID=ANY \N=161052 TS_OK。 

     然后感谢分享的license，以下内容拷贝到TXT，然后修改一下后缀名为".dat"即可。剩下的就不啰嗦了。哈哈
