Error building Player: CommandInvokationFailure: Unable to kill the adb server.

Hello, I bought a windows 8 computer and I installed Jdk 32 bits + SDK android with the last build.
My unity find my SDK directory but it says that it can't kill the adb server.
That error is new for me and i don't find nothing on internet.

Anyone knows what is happen?

Error building Player: CommandInvokationFailure: Unable to kill the adb server. Please make sure the Android SDK is installed and is properly configured in the Editor. See the Console for more details.
C:/android-sdk\platform-tools\adb.exe kill-server

Also the SDK manager says this sentence when was downloading the packages: Stopping ADB server failed (code -1), but it continued installing the packages.

Thanks

 

Kind of a late post but I hope this will help somebody.

My editor displayed the same error when I tried building on android. It had an extra line after the error log saying that the server was not running.

This was my fix for it:
1. I manually went to the folder where the adb.exe is and started it, it'll start as a process in your task manager.
2. Tried to build it again and it works!

 

I'm currently having this issue too.
Anyone else got solutions?
I have already tried aliken9's solution to no avail. The ADB process is already running on my machine.

 

Same Error !! Please HELP!!
