MATLAB: Install older versions of MATLAB

installationmatlab 2012b

I am trying to install 2012b based on this instuction:
https://www.mathworks.com/downloads/web_downloads/select_products?dl_action=choose_products&platform=win64&release_name=R2012b&tab=f
but when I am selecting a folder it says there are files from earlier installation and it does not point out to the file. Also the only files in that folder are the ones that I downloaded from there.

Best Answer

When does the question for selecting the folder occur? During downloading or during the installation? Do not install the Matlab application into the folder you use for downloading. I've choosen the default location of the installer successfully, so I suggest to try this.
