I think this post is in the wrong place but I find no way to simply delete it. Sorry 'bout that.

Can't uninstall because it does not show up on list of installed Programs and Features.
Can't delete because it tells me it is open somewhere even though it does not appear on Task Manager.
Please, someone tell me how to get rid of this program.
(HP Pavilion dv7, Win7 Home Premium 64bit)

you have to restart PC. and just delete the Kdenlive extracted folder.
kdenlive is an application that not require installation.. (like a portable)
