installation Folder

Hi

Sorry for this lame question, but I can’t handle with FCKEditor installation. According to documentation I should unzip i upload files into the root folder of server. So I did it. I uploaded fceditor folder to main folder of server. Then I started an installation/upgrade on domain.com/install and I couldn’t find this plugin in this list. Where exactly should I uploud folder to make the installation correctly?

Thanks for the tips.
