No registration for type lApplication could be found

I'm using trados Studio 2024 and I'm trying the first time to open a WorldServer package. I have downloaded the correct compatibility file (WorldServerComponents_18.2.2112) but when I try to open the worldserver package I become this message: No registration for type lApplication could be found. How can I solve this problem?Can you please help. My current version is TradosStudio 2024 SR1
