all: 我将我的keil MDK版本更新到最新的V5.37，然后我发现该项目无法再构建了。由于V5.37不支持编译器5并设置默认编译器为编译器6，所以我用独立补丁安装了编译器5（Arm编译器版本5，V5.06 update7），然后将编译器5添加到keil中，设置编译器5为默认编译器，但是keil无法编译工程，编译输出如下：
*** Using Compiler 'V5.06 update 7 (build 960)', folder: 'C:\_AnZhuang\keil\Keil\ARMCCv506u7\Bin'

从构建输出来看，这意味着 keil 许可证不正确。但是我尝试了由注册机生成的每种类型的许可证代码，但所有这些许可证都失败了。
所以，有人有和我一样的问题吗？以及有什么解决方案或建议可以尝试吗？非常感谢。

我遇到了同样的问题，尝试在环境变量中定义路径，将其安装在不同的目录中，...；他们都没有工作。
最终，在他们自己的文档中遇到了这个页面： https://developer.arm.com/documentation/ka005073/1-0/?lang =en
尝试将ARM编译器V5安装在这个路径：【Keil安装路径】\ARM\ARM_Compiler_5.06u7
对我来说是：C:\Keil_v5\ARM\ARM_Compiler_5.06u7
然后将路径添加到Keil的ArmCC Path中，如下所示： Keil ArmCC Path: add compiler
