Can't install Corel Painter Essentials 6 because another version is installed

I had Essentials 6 installed in the D: drive in my computer, but the memory broke and I had to change it. Now I tried reinstalling the program but the installer tells me that I have another version present. I don't know what to do there isn't Corel Essentials 6 even in my installed programs list, I tried deleting some files but nothing.
