ADB error: cannot connect to daemon

Question

I need help to get ADB working on my PC (win7 64bit) with the Samsung Galaxy S2.

I have installed the drivers coming along Kies, I think under sub folder \"25_escape

Answer 1

If the above methods did not work, (such as restarting, killing, rebooting, reconfigure, updating, permissions .. etc) the bug might be in the last opened files tab. I had a file I was accessing from data/data/... and whenever I opened A.S, the panel always showed the error. Just close the tabs and restart AS.
