Hello Norka Ferreira 

You can start by downloading Studio 2015 from the Downloads section of your RWS account (oos.sdl.com) and then run it normally. If the normal installation doesn`t work try the solutions from this articles: 

Please try to install Studio 2015 manually: gateway.rws.com/csm

If it doesn`t work, try the solution from this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0036431

Once it`s installed 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 follow these steps before activating the license: In Windows search bar type "Device Manager" and open it and then go to: Network Adapters - Action - Add Legacy Hardware - Install the hardware that I manually select from a list - Network adapters - Choose a network adapter (Microsoft > Microsoft KM -Test).

Then, activate your license offline as described in this article: https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0039784

Thank you,
