I'm trying to upgrade to AVG 8.0 from 7.5 but it keeps failing with an error
Local machine: installation failed
Error: Action failed for registry key HKLM\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Windows: creating registry key....
Error 0x80070005
has anyone had this problem and what can I do about it.
thanks, Bill
