Windows 7: USB Problems: "Can't install driver, access denied"

USB Problems: "Can't install driver, access denied"

Okay so i recently bought myself a lovely new camera and i was eager to upload my pictures to the computer.

Upon installing (correctly) the software that came with the camera on CD, i plugged it in and ofcourse, my computer doesn't recognise it.

Its a Canon EOS 700D, and after googling things for a few hours i've came across the fact that canon doesn't communicate with windows 7 very well and there is NO specific drivers that i can download.

When i try to fix this problem by finding my camera in device manager and doing the automatic search for drvers, my computer appears to be downloading a driver and then i am met by that error message " Access denied"

So i accepted defeat and went to a local tech shop and reluctantly bought myself a SD card reader as i'd been told thats the easiest way to get my pictures across.

So i get home and plug it in and again, the same process takes place:

I plug it in, it tries to install the device and prompts me with that typical error saying that installation has failed. So i go to device manager, find my device and try the same thing again and it begins downloading a driver then gives me access denied.

I'm lost and frustrated and refuse to believe that BOTH my camera and SD card reader are at fault here, there MUST be a fix, but i am yet to find one on my own

Thanks in advance for any help.

Can you elaborate on the 'Access Denied' message, or better still post a screenshot.

I'll add one more possible solution as i've seen malware also cause Access Denied in a few different recent threads. Try running the 3 malware tools listed in post #2

That should resolve any issues you have with usb devices unless it is hardware related.

is the problem SOLVED ?

To whomever noted this "problem" as solved, are you sure the problem posted by the original poster is solved?
it does not appear to be solved to me.
I have the same 'access denied' problem with W8x62 and a USB2 HP printer driver. I have used about 8 hours of my time, and have yet to find a solution.....
