Vista Ultimate wont update drivers

Hi Im having a problem updating my Nvidia Drivers to 180.48 I download them, extract to a folder and run the application it all seems to go normally. Restart the computer and all is well. except that when i look at what driver I am using its still telling me, it seems for some odd reason the old driver is not being replaced.Ive tried unintalling the driver completely and Vista automatically installs a driver when my computer restarts, but its not 180.48 that gets installed its 7.15.11.

Any Ideas ?

Woops realised this is not the place for the topic… reposting it in the proper forum

just a linux-user observation:

the last 5 numbers of are 180.48
