Bad WordPress folder changed

I reinstalled my XAMPP but I totally forgot that one of my projects is still there.
So, I moved the folder from the htdocs from the previous xampp instalation (I never remove it on the Uninstaller wizard, luckily) but when I open it asks me for installing WordPress (again). Probably it’s something with the database, I still have the mysql/mydatabase folder (with the ‘data’ folder in it).
I know it’s a dummy mistake but I totally forgot that project, thanks.
