Windows 7: netgear wn111v1 problem with driver

hi
I have problem i bought new laptop with windows 7 home
I using USB wirelless adapter is it Netgear WN111v1
I have now problem with drivers I that doesn't work.
I want now to uninstall this drivers but I can't do it because i have some 1612 error
I use google and I read that this is some problem with register files (extension msi) so on forum (I don't remember adress) I found program RegCure Register Clearen.
I run this program and after scan it found somethinig about 140 errors and repair it.
Now I want to erase this previous drivers installation (by Control Panel) but I can't because I still have this 1612 error.
I can't install new drivers (on other forum I found driver netgear_setup_2_1_ww.exe - some men wrote that this one will be ok for windows 7 and my version or netgear) because when i'm starrting setup installator want delete previous drivers but that can not happen because other error appeard.
I don't know what to do ;/ Can you help me somehow?
I bought new laptop yesterday with Windows 7 and I can't use it [it's mean i can but i don't have internet] I need this netgear adapter to have working internet.
please (again) help me
