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

I had a couple of things open that prevented ADB from properly running. Specifically, I had BlueStacks Tweaker (to kill BlueStacks which runs in the background) and another program. Both use their own bundled adb.exe version for issuing commands. I was then also using my system's adb.exe. I had to close the other two programs in order to solve the problem. Restarting my computer would've also solved the problem (by closing those programs for me lol).
