Hello.
I got this issue after reinstalling my OS. It's Windows 7, same one as before. Old version of TH also had this problem for me. Decided to back to D3 for a while but new version also not working for me
I did everything right, but literally after a few seconds after launching TH process is vanishing from the Task Manager. Idk what to do
Thanks!
Edit: i don't have any anti-virus software running and also my firewall is turned off.
