Builtin or standalone version?
For SecureLine (for PC), you don't have to "delete device" (after formatting the PC, uninstalling the software, or other situations) to use your license in another one. Just download it, insert it and use it.
But, about the issue
"click download license it does not download", it's true. We click and nothing happens, the button just become "blurred out".
Like this:
Someone, please, report it to Avast?
Thanks!
