I am not sure how. The situation escalated a lot.
I already uninstalled avast. So I cant access the UI. I would gladly install it again, but I don't know the key. I don't know what email is associated with my avast products, and apparently I don't have an avast account, since none of my email are recognized. Also the email I think it may be associated with it I long lost access to. I do have all avast products installed on my SSD, but trying to solve the 100% error I ended up with a bigger issue and now I can't boot the SSD. I can access it through windows explorer on my HD, but I don't know if there is a file there where I can copy the keys.
I was about to create another topic to ask support to help me retrieve my keys/account when I saw your reply.
I do still own the same credit card where the products subscription are linked to.
I really don't know how to proceed.
I would appreciate any help.
