can't install omega 1.5303

haruvi

hello.
well i had nvidia 56.72 installed with geforce 440 mx.
i installed the omega driver like the manual says (without uninstalling the original drivers), but after the computer restarted it seems like no driver is installed... no nvidia sign or any sign found anywhere. the driver name IS written in the -
Device Manager -> display driver properties. but it looks like it is not really installed.
to make sure, i tried running a game but it didn't work.

i tries some things like uninstalling all drivers and then install the omega one. also tried to install nvidia 53.03 official and install the omega drive on it.

i got the same results...

what can i do???
