Android studio build application error: protocol fault (couldn't read status)

I re-downloaded Android Studio (latest version) and installed it. I must precise I had an ancient version which I deleted some months ago (I did not use it anymore).

However, I encounter a problem after installing this new version. When I try to run my blank application, I saw it started the emulator but nothing starts. Indeed in the console, I can read :

error: protocol fault (couldn't read status): No error

'C:\Users\[myname]\Android\sdk\platform-tools\adb.exe start-server' failed -- run manually if necessary

I have tried these solutions but none of them worked... :

The command adb kill-server and then adb start-server give the same output : error: protocol fault (couldn't read status): No error

I, of course, tried to restart my computer.

I am running on windows 8.1

Edit: After the comment of igor_rb, I tried : set ADB_TRACE=all then adb kill-server and adb start-server, here are the information

try set ADB_TRACE=all in cmd and than run again adb kill-server + adb start-server. It can helps to find issue. - igor_rb
I edited the post to add the output, thanks - FabRoussel

Possibly, you are use too old version of adb.

Try to update it (Tools -> SDK Manager -> SDK Tools tab -> Android SDK Platform-Tools)

Surprinsingly, creating a script which contains the following code and executes each time my computer start solved the problem : 

adb kill-server
adb start-server

I added the script here : C:\Users[name]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs and it runs at each start (before I can open Android Studio)
