Cannot Install Usb Controller Driver

Cannot Install Usb Controller Driver

I have an acer v3-771G laptop with Windows 7 on it.
My USB was working fine for over a year. But lately it has been acting funny (will not recognize like any of my external drives in the sockets) so I am trying to reinstall the USB drivers. I downloaded the USB drivers from acer's downloadlink ((USB 3.0_Intel_1.0.4.220_W7x64_A)
But I can't seem to install the driver at all. I first tried to use the setup.exe that was included in the driver pack but that turned up an error saying that it was unable to install one or more drivers and it just quit.
I also tried to install the USB driver via my device manager. Under the 'Other devices' nodule, I saw several USB controllers, and I selected one and clicked update driver => selected browse => pointed it to the USB 3.0 folder and it did 'recognize' the Intel USB 3.0 extensible host controller but said 'Access is Denied'.
Please someone help me. I have no clue what to do now

Setup Usb Controllers Windows 10

For one time, I removed the USB device and started up Vista. That is when the problem started occuring for me. On the next restart, when I connected the USB devices, it would not identify them as already installed. Any new USB devices that I connect, it can not install anything at all. Cannot install the driver using the USB drive. But you cannot reply to this thread. Right-click the first USB controller under Universal Serial Bus.
