Update failure

I'm using SDL Trados Studio 2019 SR1 version 15.1.43919.0.

 

And I want to update it to 15.1.48878.2. After downloading, I tried to install the latest version.

 

But, it only repeats to restart Window 10 without any progress of installation. Furthermore, MultiTerm has the same issue.

 

Is there anyone who can help me out?
