I've only had issues with the software for school in the nights before I had to submit work. For exemple, I recently had to give back a work on matlab. And at 9 pm it didn't show up in the windows menu. So I tried to run the installer that was too long, until I found out you had to use a flash drive. Then it returned a lot of errors saying I didn't have the modules. And I have the same issue with every damn software. What should I do ?
