As in topic, please help

I've tried to install it manually (no AutoMODs) regarding to instruction, but it won't show up in drop-down menu in ACP. I've noticed some destination directories are not correct, like
/language/en/mods - I have no /mods subdir, so had to create it manually, but other files like captcha_recaptcha.php do exist directly in /language directory
or
/includes/captcha/plugins (I have no /captcha and /captcha/plugins subdirs, so again - had to create them separately)
All attributes are 775.
Any good news, please ?
