Trail Version - Invalid Activation Key(379)

I am trying to use the trail version but I am getting this Invalid Activation Key (379) error.

I just created a new gmail for the trail and never installed on any other device. I created matlab account and downloaded the trail version installer which gave me this error when trying to login to install

A new error Licensing error: -9,57 was encountered when the installation was completed somehow.

Hello Raman,

This error is caused due to an issue with the Activation Key. You might find it helpful to refer to this MATLAB Answers thread, which discusses a similar issue:

Hope this helps.

Yes, thank you for the thread. I have tried that but none helped. I re-downloaded the installer and with my credentials it got installed. BUT, when I try to open it I get another error Licensing error: -9,57

I don't why this is happening.
