Crossfire Install Problems?

Hello to all

I am having some problems installing CrossFire on my PC after some gamefiles were corrupted by an Anti-Virus.

The Anti-Virus (AVG) Picked up the Crossfire.exe as a virus and removed it, so im re-installing from fresh.

When installing from the latest setup file, AVG alerts me of a Virus in the Temporary folder, coming from the setup file:
http://gyazo.com/a81e096ea47b582c0a3ce43940a917a8

And after Pressing Allow, knowing its coming from a safe source, the setup says this:
http://gyazo.com/7993f8744f6c97c026ff80a5da861779

Pressing Retry comes up with the same error, and pressing ignore brings up the same error for every file it is trying to install.

Any Help?

Thanks
