Vista - Dreamfall Protection System Error! pls help!

I have this game, Dreamfall The Longest Journey. now I got a new computer with Windows Vista Home Premium 32bit. before I had Microsoft XP and there was no problem playing Dreamfall except it went in slowmotion... today I installed dreamfall and there was nothing going wrong untill Protection System came up when installation was done and I clicked on the game icon. this is what it says:

Protection System
To launch the application, u need to install additional libraries on your computer. Would you like to install them now?

No-nothing happens
Yes- Error. To install application you must have Administrator privileges on your computer.
what should I do?? when I click information it just collect a whole lot of ununderstanding information! if I click OK nothing happens. is there something that needs to be done? I really appriciate answers!

give it administrator priviledges then by right clicking the installer and running as administrator.
image below - i know this is GTA4 but its the same thing you have to do with the file on the disc or the executable.

thank you so much! but after, vista blocked the game cuz of the protection system but I managed to solve it. thanks yet again!
