So I decided to pre-download Diablo 3 for the release date.
My downloader is at 100% and has been for some time. I tried running the now-complete that was downloaded and it's telling me I cannot due to it being in use by another program (likely the downloader). The Blizzard downloader is a P2P client, even if it has finished downloading it stays open to let others download from you. The downloader is based on Bit Torrent, an extremely robust protocol for downloading.
That means Task Manager shows 32 tiny little performance graphs. NET really fast (lots of C /CLI these days), and is killer for working on all that multithreaded rendering code.
Your solution really did work because i can see it downloading now, so thanks alot man! I have been doing this for about an hour, following each step over and over...After leaving the installer for ~30 minutes, it finally brings up an error stating it could not run the Blizzard agent; This gives me an error code - BLZPTS00007 - which gives me a few more google hits including a seemingly official guide on how to troubleshoot agent issues on Battle.net, however performing the steps listed under 'Advanced Troubleshooting' still hasn't resolved my problem.How can I get past "Updating setup files..." when reinstalling Diablo 3, and what is error BLZPTS0007? It also works for the "Updating files..." progress bar error. page=1 TL; DR noob friendly version: This worked for me, I was finally able to log in after 1.5 days of failed attempts. Go to WTF/Find and edit SET gx Api "D3D11" to SET gx Api "D3D9" Start Launcher.Update - Possible fix for 15544 Update Okay, so I couldn't log in after the 15544 Update. If the progress bar is stuck, try it a few more times.
