Just to be sure, do you usually run Anki from a shortcut?
Could you try running anki.exe in Anki folder (C:\Program Files\Anki)?
Yes, i usually run from a shurtcut, but i already tried to open in Anki folder and it didn’t work 
Doesn’t work through shortcut and doesn’t work through Anki folder. So far the only way i can open it is through the command that you taught how to type.
My Anki won’t open. I already installed the windows upgrades and uninstalled Anki and it didn’t work. It happened today. Yesterday was normal
I have the same problem, Idk what should I do
I have the same problem too! I tried to uninstall and install again four times but it’s not working… it started today, yesterday I used it without problems
Can you run the following commands and post the contents of the anki-debug.txt file that will get created on your Desktop?
cd \program files\anki
anki-console > "%USERPROFILE%\Desktop\anki-debug.txt" 2>&1
(I suggest trying the same to others who face this problem)

This is identical to the output I get, though I have no problem running Anki 2.1.29
Have you tried opening mplayer.exe ?
Tried now, didn’t work too
check if anki is open in task manager. check both Apps and Background processes (it’s more likely to be open in background)
if it’s open, simply kill the task and try opening anki again.
if that’s not the case, i have no idea what might be causing it. 
Is not opened
I have been got through this same problem since today earlier. Yesterday It was working properly. I installed the previous version and didn’t solve.
I just oppened run as administrator the follow file on the Anki’s directory :
C:\Program Files\Anki\anki-console.exe
At least I could practice my decks with the console windows that oppened the app.
Meu problema começou hoje também, já tentei instalar novamente, instalei a versão antiga e nada.
Torcer para arrumarem e que não tenha perdido meus baralhos.
Guys, i finally solved the problem here. What i did was:
1.Uninstall Anki and restart the computer.
2.Download and install the 32 bits version (it worked to me and to my friend who gave me the suggestion)
This friend who gave me this suggestion said that Anki is not opening due to a kind of incompatibility with Nvidia GeForce graphics card.
Deu certo aqui com a versão 32 bits.
O meu voltou a funcionar com a versão 32 bits.
Instala a versão 32 bits.

I got it with the 32 bit version. I advise you to backup the decks
Assim como os colegas acima, até ontem (03/08), estava tudo funcionando normalmente, mas hoje nada do programa abrir. Já havia tentado de tudo (permissões no firewall, modo de compatibilidade, executar como administrador, instalar versões anteriores 64 bits…). Pra mim, funcionou desinstalando a versão 64 bits e instalando a versão 32 bits. Nem foi preciso reiniciar o computador.
