Brand new user here. Try as I might I can't seem to get WinFindr to 'Run as Administrator' in spite of repeatedly starting the program by right clicking and choosing Run as Admin. Even doing that, I keep getting the message (on About page) that I am running the program without administrative rights. Any help will be appreciated. Files on my older PC are in desperate need of culling. Thanks!

What version of Windows are you using? Is your local Windows user account the administrator account or restricted? Do you happen to be using any third party antivirus programs?
