OMG where to even start with this one....
First off you don't tell anything about any kind of error you may
be getting when installing the driver all you say is that it doesn't
work at all and that you can't finish the installation.
You also give no stats on your computer or any kind of a dxdiag or any other system information here. how do you expect anyone to be able to "help you"
if you don't give the people here enough information to be able to
try and help you.
The message that you posted "xtremePc" is utterly useless and gives
no one any kind of information about the problem or about the computer system you are on to even start to try and diagnose this problem. All you say is that you have a Maximus_IV Motherboard that is not enough information!
Did you at least read the topic " Troubleshooting Common AMD Catalyst Driver Install Issues"
And this one as well "Clean install AMD drivers"
Also if you are going to post a problem here use this template
and fill in all the information requested in it.
