problem with the launch of matlab

hello

I installed the 2013b version of matlab to do an exercise and now I have also installed the 2020a version. but my problem is that matlab 2020a doesn't manage to launch it but the 2013b version launches very well.

Could you help me to make it work, because I have to deal with it.

hi

I have installed two versions of matlab, i.e. 2013b and 2020a. But I have a problem, it is that the 2020a version manages to launch correctly, on the other hand that of 2020a does not manage to launch.

Please help me.
