Android ADB drivers installation error I am trying to install the usb adb drivers. I turned the debugging mode on in the settings of my phone, connected to the PC. I click update drivers and manually selected the folder where the drivers are placed. For some reason the drivers installation fails and Windows gives the following error. Kindly guide me what is going on and how can I solve this issue? I am on windows 7

Drivers Installation error

It sounds like your drivers are fine
Are you trying to use ADB with the Android SDK or are you using it for running commands etc... 

If you are using ADB to run commands and ADB isn't installed as a recognized command ( universal installation )   

then you'll need to run adb in it's directory.    

Unzipping Easy ADB V1.zip will give you a few versions.


Auto Authentication ADB - Used for automatically asking for
authentication.
Normal ADB - Old device's  ... new device's will say Offline without
the authentication.
Fastboot
OPEN ME.bat


Double click on Open Me.bat to start a command window using the desired option, this is a simple batch menu to start a command window in the desired directory, right click and edit it to customize the colors etc.... 

Make sure your device is recognized as Android Composite Device etc.... 

And run adb devices from the command window you opened.


  If you've chosen the Auto Authentication version, you'll need to accept the connection on your device.


Sometimes you will need to do this on the normal version as well. ( it's just an old version )

Hope this all helps simplify the process ... 

Using the SDK 
You should only download the entire Software Development Kit if you actually plan on developing software...

It should automatically use the correct directory in Android Studio, without modifications.

I personally use the Easy ADB files - I just slapped the .BAT file together to make easier for beginners to navigate without using cd.
