Do you have a Keycode? Also is it for Windows 7 and above?
To download the installer for the above click here: http://anywhere.webrootcloudav.com/zerol/wsainstall.exe
If you already have Webroot Installed all you have to do is put the new keycode and Activate: https://docs.webroot.com/us/en/home/wsa_pc_userguide/wsa_pc_userguide.htm#UsingYourAccount/ActivatingKeycodes.htm%3FTocPath%3DUsing%2520Your%2520Account%7C_____2
