Aida64 reports a "test failed" if the aida_bench64.dll is detached from aida64.exe

[sp00n]

The dll can become detached from the aida64.exe process, in which case Aida64 reports a "Test failed" in the stress test window even if the stress test process is still running fine.

It's possible that this happens only if the Core 0 CPU 0 bug happens, so it might not be an actual issue.

The script now tries to gracefully stop the stress test process by sending a keyboard command to the Aida64 window, and only if that fails kills the process. If the stress test process is killed, it will also quit the main window process.
