问题
如图，这个区域无法显示你的插件，空白的，就无法进行下一步
解决方法
1、重新安装 FreeMaster，最好安装在 C 盘，我就是这样解决的
2、
如图中所述试试
Basically, the installation process is the same as running the
“c:\NXP\FreeMASTER 3.0\FreeMASTER\register.bat” with administrator
rights. If re-installation does not help, can you try to run this file
manually in a cmd console window (started as administrator) and see
what it prints?
