I downloaded avast to USB memory, then installed it to computer what is not on network at the moment.
Then i connect it to internet and try to online register, but nothing happens (i tried many times, leaving computer alone up to 15 minutes) then i try to insert license key as instructions says, but then i got this (cannot now remeber excatly error message, because computer is now on my home and i am work at the moment) but it says that some file is missing... and cannot register it.
Should i remove this installation totally and re-install it?
OS: XP Home, with sp3 installed, Computer is Fujitsu Siemens Scaleo T
