I have an accademic licence and for years I've runned MATLAB on my pc, renewing it yearly. Nevertheless, since late 2019, I'm no more able to run the programm downloaded from the official MathWorks site. In fact, after extracting the temp folder and running the installer,it appears the MLab logo on the screen, seemingly froozen for hours till you force it from the Win task manager. I've also tried to remove the previous versions with all files on my system disk in vain.
In addition to that main issue, today I'm not even able to unzip the folder. The job stops with this message: «Can't create output file: _temp_matlab_R2020a_win64\ui\install\installservicehandler\dijit\icons\images\commonIcondsObjActDisabled_rlt.png»
That's it. Thanks to anybody who can help me
