Cannot Un/Install AMD Catalyst - Please help!!!

[Oggi-Wan]

Following happened. w7 Premium 64bit
1.Instead of VGA updates I installed an APU Driver.

2.I set the the 3d gaming settings on "Optimal Performance".

3.I rebooted the pc, after that it seemed like it was in safe mode.

4.No game worked.

5.I uninstalled CCC and then tried to install it again, didn't work.

6.Direct X 11 won't install.

7.I saw that There is a yellow triangle with an exclamation mark on the graphic card in the device manager.

8.I downloaded the original driver for the graphic card, it still won't install. It gets stuck at Visual Redistributable 2012 c++.

9. I tried installing with administration rights, still nothing.

10.I re installed visual 2010 to no avail.
EDIT: I actually can't uninstall CCC, although it says it's uninstalled at the end of the process, it's still there in Control Panel Add/Remove Programs.

Here's the error log.

Re-directing the graphic card driver in the device's manager at least made the PC normal again, but I still don't wanna mess around with CCC on this PC.
