Wix uninstall does not remove files

I have a C# project with a WiX installer.

When I install my application, all is working. I Have :

• my compagny folder in program files (x86), containing my application folder and the drivers folder.
• the shortcut in desktop
• the shortcut in start menu

When application is installed, I can run my msi and I have an option to uninstall. But when I uninstall my application, only the drivers folder is removed (MyApplication_Drivers). I still have my application folder and the shortcuts.

What I'm missing ?

There is my code for product.wxs (entire code cause I don't know where the problem come from):

EDIT :

• An old version of this code was perfectly working

• I printed log while uninstall and this line seems to be related to this problem :

MSI (c) (E8:BC) [10:58:16:769]: Disallowing uninstallation of component: {one of my guids} since another client exists
