I have such a problem with the engine Booot 3.6.1 x64. I play using software Cutechess v1.1.0.f.1.0 and a window appears when loading the engine into the tournament. Does anyone know how to solve this problem. Thank you in advance for any information.
I can run a tournament including Booot 6.3.1, with Cutechess Cli, without problem. So I don't know why it doesn't work with you. Not yet tried with Cutechess GUI.
Maybe an antivirus issue? Maybe you could try to exclude your chess engines folder in Windows Security settings?
