I purchased a license before I made an account, but when I purchased the licence I entered my email address incorrectly on accident and now I am unable to open my license key file because it has been “modified or corrupted”. I bought a 2 year subscription and I wouldn’t want to have have to re-purchase it. Please tell me there is a way to recover the file!!!
Where did you enter this email address incorrectly ?
Presumably not when purchasing the license otherwise you wouldn’t have received the email with the license file attached.
If the issue is with your my.avast.com account and an incorrect email address, log on using that incorrect email address and password. Now click that email address and some settings will appear - Manage Email is the option you want.
Here you can add a new email (the correct one) you will need to validate this email address. Once you have done that log on to your my.avast.com account and select that new email address as the default email address.
