Aerial.scr file can't install

[Alenin1999]

Hi So i been trying to install aerial on my windows and the aerial.scr keeps saying its AutoCAD Script File and I cant figure out how to change it. I have fully uninstalled AutoCad from my machine and it still exists. Because of that nothing happens when I run it. It does show up on my screensaver options. Also I tested my other user account in the same machine and it works fine, its just my user used to have AutoCAD and I cant run scr file. Could anyone help?
