I had to delete folder one more time, then it started downloading. If the progress bar is stuck, try it a few more times. I got the Cannot locate correct file error too.įind and edit SET gxApi 'D3D11' to SET gxApi 'D3D9' Okay, so I couldn't log in after the 15544 Update. This worked for me, I was finally able to log in after 1.5 days of failed attempts. The first time it crashed for me the download started all over from 0%, but the next 3 times it continued from where it crashed. Just go to the task manager, kill agent.exe again, delete \ProgramData\ again, and restart launcher. Sometimes the launcher will crash while you are updating the files.If it's not moving, then something else is causing the problem for you. The progress bar might stay at 10% for a while, so wait at least a few minutes. This might not be necesseary, but do it anyway. I actually deleted all networks from there. Under Dial-up and Virtual Private Network settings delete all old networks. You can click on the little blue (more) link at your battle net account to get your local client like enGB. If you can't delete it you have to open the Task Manager and kill the Agent.exe application. Delete C:\ProgramData\ folder if it still exists.Disable firewall and remove router if possible just to make sure those are not the ones causing the problem.It also works for the 'Updating files.' progress bar error.
