Avasta 4.7 update problem

Hi All

I’m using Avast Home 4.7 free edition on my home PC which is not connected to the Internet.
I usually update the programme by downloading updates from this website. But my Avast refused to install the latest update showing an error and saying that I must update the programme first…how can I solve the problem
Thanks

The new database scheme requires a program update.
You must download the latest setup 4.7.1074 and you’ll be able to update your virus database after that.
Welcome to avast forums.

Thanks a lot!!!
I’ll try

Where is that update package? I mean 4.7. 1074?
