Problem med mjukvaruinstallation till Antec Kuhler H2O 920

Hej, Sweclockers! Jag har tidigare ställt samma fråga i tech support guy forum utan svar, men samma problem återstår, därför skickar jag samma fråga oändrad, på engelska. Hoppas att det är OK.

Hello there, I just bought an Antec Kuhler H2O 920 and everything's correctly set up, I'm 100% certain of that, but the software can't be installed, and therefore neither can the drivers. This is the error that I get: http://i.imgur.com/1VKeAlM.png
I have logged the Installshield Wizard installation and here is the log file: http://pastebin.com/9j1BbWUQ

Nothing is to be found at the device manager, and I've tried installing the software on my laptop which went through without problems. The issue most likely lies in the InstallShield Wizard installation, which I managed to log for you guys. Hopefully somebody can understand what's going on in that log file and find a solution to this problem.

Here's some information about my system:
