Error Installing AVG 2012 free Edition

Hello!
Has anyone been having problems installing AVG 2012 free edition?
I tried installing it, but a “connection failed” error keeps on popping up and the installer closes.
So I tried installing the full version, but I still got a setup error with code:0xE001003D.

AVG. .AntIvirus
Setup Error
Severity Error
Error code: 0xf00W03D
Error Message: Specified file was not found.
Additional Message: An internal MSI Engine error occurred.

Can someone give me advice on how to fix this?
Thank you!
