Win7 Arduino Mega 2560 driver installation Failure solution

Because of playing the four-axis APM with the flight Control Board, and it needs to install this driver, once used in Win8, but because the WIN8 has a corresponding digital certificate protection measures (this should be the case, because it is not clear for a long time), so that I always need to press SHIFT to restart the computer to turn off this feature, Later installed Ubuntu, with the Ubuntu boot Win8, so that the direct result will not be out of this option, so on another computer on the abandoned Win8, instead of Win7 and Ubuntu coexist, Win7 no such protection measures.

Now, let's get down to the chase.

First, to know the type of error, I am, can not find the system specified file,

Most of it is reported this error, other errors can follow this attempt, no fruit to find his way.

Since the display system can not find the specified file, then we need to know, it is looking for a file, we have to give him a (most can not find things because of the ghost version of the people, there are limitations),

1. Find out what file it finds

We open the catalog file, C:\Windows\inf\setupapi.dev.log.

Here the bread with the driver installation of the log, if you just installed and failed so should be at the bottom, if you are not, then use ctrl+f shortcut key, keyword input MDMCPQ should be able to find, and then find the following line,

At this point we have solved the first step, that is to find the required files,

So we'll find no mdmcpq.inf_amd64_neutral_ under the C:\Windows\System32\DriverStore\FileRepository. B53453733BD795BC (may be different later, depends on your log) This folder, but we need at this time the file (folder name may not be the same, to its own), copy this name to create a folder Mdmcpq.inf_amd64 _NEUTRAL_B53453733BD795BC, and then put the missing files in this folder, things can be their own online search, I also here to my pro-test of the possible Baidu Cloud share Http://pan.baidu.com/s/1jIpYO1C, Inside the system according to their own situation choice, want is these two,

Copy it into the folder you just created.

Re-update your Arduino Mega 2560 driver and you'll find out,

Here by the way to an Arduino client, which contains drivers, HTTP://PAN.BAIDU.COM/S/1KVOAUDP,,, recommended to use the suffix. exe installation version, with driver, or it

Well, the conclusion will not be written, the small plane is a pit, but the small plane will continue to fly
