以前用的Keil4注册机keil_Lic_3.2注册可以，

编译也可以，

就是在线仿真的时候仿真一次就失效了，

需要重新破解，用起来很麻烦。

这款注册机破解后就没有问题了。-Previously used Keil4 RI keil_Lic_3.2 up can, you can build, that is, the time-line simulation of a simulation on the failure, the need to re-break, a lot of trouble with it. RI after this break is not a problem.
