hi there,
i have met this issue just recently on several windows 7 platform (licensed version). laptops and desktops having the same issue like: it can not install even mouse or keyboard driver(this is only the message i've got, but the mouse and keyboard is working fine), even normal usb flash can not install the drivers. i have one desktop pc that is newly reformat, it is working fine all the drivers were installed properly, im sure with that, but after maybe 1- 2 weeks. this "access denied" message is coming while i'm trying to update the drivers.it is already log on the built-in ADministrator account. so i think i've got all the privileges to make some changes on my pc. this is a stand alone pc, not connected to any domain. is this some kind of a bug on windows 7?. because this is the first time i encountered this kind of problem on windows 7. i tried several methods to figure out the solution but everytime i'm ended up on reformatting the pc. :(
please help.
