Plants vs Zombies GW2 dosen't launch

I saw the free 10 hours of graden warfare so why not. I downloaded the game and during the installationn procces no window popped up not sure if thats what is supposed to happen. Than I launched thre game and nothing happend! The procces in task manager appeared but nothing. I closed it and opened again restarted my pc and dosen't launch still. Do I have to reinstall it? I hope no because the downloading took me around 1 and a half hours ☹️
