[Unable to delete the unzipped installer folder]

Hi,

I am unable to delete the folder & contents that were created when I unzipped the installer.

I get this error popup:

"Folder access denied: You'll need to provide administrator permission to delete this folder

paint.net.4.3.7.install.anycpu.web"

And of course, when I click continue, it just keeps popping the same thing.

 

Could someone provide some easy to follow instructions on how to overcome this please?

Thank you
