Hi, I'm in a similar situation as these two threads:
Trados 2022 activated on new laptop, but not 2021
After receiving a new laptop, I installed Studio 2022 hoping I wouldn't need 2021 anymore. This was fine until I realized that the Embedded Content XML file filter had been removed from 2022 and I need it to update file type settings on our version of WorldServer.
Installed Studio 2021 and it won't license. I tried deactivating my 2022 license and applying it to 2021 but of course this didn't work. Reactivated 2022 without problems. Still in 2021 trial but I need a fix as my trial is running out!
Thanks for any support!
