Successfully installed on a pc and android but the other pc that I bought the 2020 package for is failing to install. The pc shows on central as at risk but there is no sign of it on the actual pc. after the first attempt when bit defender requested the removal of avast free to install. this was done but then bit defender just disappeared. I have tried to re download the link and install it myself for my partner and the window doesn't even open from the download link.
