Hello Emmanuelle Jeannot 

Please try to reset the license from your RWS account as described in this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0038545

Then try to activate it offline on the new PC: https://sdl.service-now.com/kb?id=kb_article_view&sysparm_article=KB0039784

Thank you,
Sorin

Thank you Sorin,

I had lots of problems instaling the extra licence on my laptop last September and did more than 3 resets - apparently the problem was because the laptop name had a special character in it (é)  although I have never heard or seen this explained.

Can I request an extra reset to intall Trados 2021 on my new Desktop or do I have to wait until September (would be a pain as my current computer is really at the end of its life)?

Thank you very much in advance for your help Sorin!
