How to uninstall after installing .scr file?

[aminomancer]

I followed the installation guide in the wiki for .scr installation, but the videos are jittery, so I wanted to uninstall it. But the uninstallation guide seems to only apply to .exe installation, as it mentions an uninstaller in %AppData%\Local\Programs\aerial that does not exist for me. When I do the .exe installation, it does exist, but not with .scr installation. Deleting the file on my Desktop doesn't seem to fix it either; my screen just goes black after going idle.
