To reply to Nick H’s comment: this is a 1 year license.
I installed it on my PC, did not like it, decided to uninstall it.
It appeared in both my Windows Uninstaller as well as Geek Uninstaller, so nothing shady there.
After your comment, I installed it on my secondary laptop as well, again, no problems uninstalling this.
There’s something wrong with your machine mate.
