其中，运行库的GUID可以解压 vc_redist.exe，在文件0中搜索ProductCode，会搜到两个，我们需要 ProductCode 为 RollbackLogPathVariable = vcRuntimeAdditional 的那个GUID
目前仍有一个问题，即使系统已经安装了对应的vs版本，安装程序在完成安装之前仍会去运行vc_redist(这是使用了64位模式导致的：ArchitecturesInstallIn64BitMode，如果不判断系统版本就不会有这问题)
只判断x86注册表的示例代码：
#define MyVSGUID "{EFC21A37-5640-4BE1-981A-2FD3EDA1D893}";
