Seriously, Blizz should have delayed the launch until they had all this crap fixed.
D3 works on my crappy machine, like it will update but it wont be able to run (its pretty bad lol). But when I copy over the files to my main machine, the launcher starts, but will not update at all.
The culprit seems to be the Agent.exe, i tried deleting multiple times, and ending the process
UPDATE: Now launcher or anything deosnt open, just give an error report :/
