安装完ius之后原先安装的questasim和verdi起不来了，why？？？

醉东山

如题，修改之后，verdi起来了。但是vsim还是不行。难道是license，path冲突了？？？显示的是：
Unable to checkout a license. Make sure your license file environment variable (e.g., LM_LICENSE_FILE)
is set correctly and then run 'lmutil lmdiag' to diagnose the problem.
Unable to checkout a license.  Vsim is closing.
** Fatal: Invalid license environment. Application closing.

运行lmutil lmdiag之后显示

没有vsim的license文件！！！（没装ius之前vsim verdi都能正常启动，怎么会没有license）
到底是什么原因啊！！困扰了好几天了，，，
