Can't extract DLL

Hello,

I have a problem with my Vista Home Premium. I want to play a game (Lineage 2). When I click on the launcher, it doesn't work, because "can't extract DLL". I have all the requirements for this game and with XP I have never had any problems with installing and playing. What can I do?

Thank you for your time and help in advance, Nana.

Well, I have solved the problem by clicking on opening as administrator. BUT there's the next problem:

2008.10.19 19:40:04
OS : Windows Vista 6.0 (Build: 6001)
CPU : GenuineIntel PentiumPro-class processor @ 1995 MHz with 2047MB RAM
Video : NVIDIA GeForce 9300M GS (7620)
General protection fault!
History: UOrcMove::CalculateCRC32 <- UGameEngine::Init <- InitEngine


And then: game inject hook failed.

What to do now?
