Hello Cristiana Zampolli

Here are all the steps you need to follow to transfer Trados Studio to the new computer:

1. Download and install Studio on the new computer from your SDL account > Products & Plans > Downloads.

2. Deactivate your license from the current computer from Studio > Help > Product Activation. If it doesn`t work from there try to reset the license from your SDL account as described in this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0038545

3. Activate the license on the new computer.

If you want to move any data (projects, TMs, etc) you can use an USB stick to copy them from the current computer to the new one. 

Thank you,

Sorin
