Trainer updated today for build 1.6.2, https://mrantifun.net/index.php?threads/hearts-of-iron-iv-trainer.8280Trainer activates ok, but any subsequent choices are not registered/actioned , they just generate a soft beep after a few seconds.
Try to use 1.6.2 and let me know, if issue still persist in future i recommend follow FAQ - Frequently Asked Questions by "If you are having a problem while downloading a trainer".I am having problems downloading it or extracting it....file extractors says there is no file in the download. Tried downloading it 5 times and can't open any of them. But can download and open the version for 1.6.0
