Windows 7 - Catalyst driver for HD4330 mobile - can't install, only WDDM

Hi,
I have a problem on a Dell laptop where by default windows installs a wddm driver for the discrete graphics. there is catalyst driver package with ccc (catalyst control center) available to download from AMD/dell but whatever version I tried to use, I cannot install the actual driver and the ccc, only some other software stuff from ATI/AMD like hdmi audio driver etc.- it's not offered on the list from options to install.

Even If I delete the wddm driver from device manager list before installing catalyst it does not help. restarting windows also (windows install wddm without asking)

Is it only wddm driver that I can use with this GPU ?! If not, then maybe u have some advice how to install actual catalyst driver with ccc ? Now I have nothing: no color/multiple display options etc., only pure driver (that doesn't seem to work with Starcraft2, - the only game I play now sometimes

Just found a solution to the problem on a similar thread. Didn't have occasion to check this yet but it must be the right solution as with dell 1555 and ati hd 4570 !
