@ CraigB,

There seems to be a few people here (see my link above) with the same problem, but now I’m wondering if there is a glitch. It took me quite a while and finally an uninstall/reinstall to resolve it.

@ gregg4023,

v. 2021 is the version of Avast (the current one out there now). What is your OS (operating system)? When you did the uninstall of Avast using the Uninstaller Tool, you did this in Safe Mode? Did you reboot your machine after this prior to trying to install Avast again?

Just to verify, the licenses you got were emailed to you from Avast? If you did all of the above, I would put a support ticket in. In the meantime we will still be here to assist you.
