This is very irritating to get ‘Error code: 16003 Invalid package found. Please verify that you have a valid package.’ every time when i am trying to install McAfee on my PC. How to fix this?
Mcafee have multiple variants of Antivirus and it looks like you downloaded the wrong one as per your subscription so to resolve this issue
Download a valid package file, then try installing the product again.
To do the same login to your Mcafee my account and redeem the activation code at www.mcafee.com/activate.
