Problem during Post-installation tasks

Dear team,

I started the installation of R2020a yesterday. Everything was going ok , however it has not finished the post-installation tasks since yesterday.

I am installing it in an external device. Is this normal? Should I wait? or on the contrary should I cancell the installation and re-start again trying to install it directly in the computer? However, Matlab seems to keep doing tasks/working on the installation as it does not force the log out... (see the second image attached)

Could you please be so kind to help?

Thank you very much.

WBW

Maria.
