It is possible to get Support Packages on a trial license. There are few things you can try:
- Lower any firewalls, antivirus software, VPNs, proxy servers, or anything else that may be blocking your connection/installation.
- Use the Support Software Downloader on a different computer or on a different network to download everything properly.
- Install the Support Packages you need on another computer and then copy the SupportPackage folder over to the computer where you're failing to install it.
- Look at the installation log file to see what files are being blocked and then download them yourself. I don't know know what release of MATLAB or Operating System your computer is using, so I can't tell you exactly where that will be.
