Instead of using a built in installer of a program, I went and deleted the program files of that program (used the recycle bin); it was removed from the control panel after I checked to uninstall programs.
But now, when I'm trying to reinstall this program, it says another version is already installed (despite my having checked the program files and checking the control panel for those files).
How do I go about removing those extra, seemingly hidden, files related to the program? Or how do I install this program if windows thinks this program is still installed? When I try to repair the installer file it says action is only valid for programs currently installed.
