BugDbg - is tool which can help you debug 64bit exe file, with many good features( trace into, trace over, breakpoint, Register viewer, memory dump viewer, commandline, start/stop/restart debugging, etc…).

Be aware its pre-alpha version so it's not meant for serious work. Definitely more work is needed but I think basic debugging functionality is finished.

- no installation needed but BugDbg needs Microsoft Visual C++ Runtimes
