Problem installing upgrade Trados Studio 2021

I get an error when trying to install Trados Studio 2021.

The following message appears:

An error ocurred and the program was aborted. you can try running the program again but if the same problem repeats, please generate a debug log (usually found in C:\ProgramData\SDL\Chainer\Logs) and contact technical support.

Log-file is attached.

Can someone let me know how to solve this?.

Thanks in advance.

Kind regards,

Andrei
