I just bought a 2 year license for KAV and I cannot install it. It took a while to install but when it is almost finished all the changes were rolled back and it returned an error. I ran the VRT tool twice already for full hdd scans.
I tried both kav220.127.116.11en and kav18.104.22.1686en both of them encounter the same error.
I am using a 64 bit Windows 7 Home Premium.
The installer rolls back right after the "Verifying Driver Installation" was displayed.
