I can't install the Rift Software "sorry we encountered an error during installation"

[astepaul]

I just bought the rift and when i try to install the Oculus Software (download was clean)  it give me this error :
"Sorry we encountered an error during installation, please restart the pc"

I tried everything i could see on the net like , restarting of course, deleting the "oculus" folder in c/program, trying to redownload the software, desactivating the anti virus etc... 
nothing work, so please if someone have an idea, i would welcome him as a GOD !!! Thanks a lot.

If others are still having this problem, if you have a proxy enabled in Internet options, disable that and try again.  That fixed it for me.

Did you run the setup as an admin?
