Thank you the uninstaller tool worked

It was an update from a previous version where ESET couldn't be activated either. Had to uninstall the beta version because it blocked all internet access. So no installed version right before this try. I'll look if I find remnants of the old installation in the registry or files. Edit: Found some registry keys that seemed to tie into firewall settings. Have deleted them and installed ESET again but the problem persists.... (Yes I restarted after deleting the keys)

Doesn't work for me 9.0.117.0 still can't activate

Same here ...

No doesn't activate and the Firewall doesn't work.
