This is the second time this problem happens to me today. First when I re-installed Norton Ghost (gave error 1306 and similar message as below), and just now when I tried to install Malwarebytes Anti-Malware. Here is the detailed error message:
Error writing to registry key: HEKEY_LOCAL_MACHINE\SOFTEWARE\Microsoft\Windows\CurrentVersion\RunOnce
RegSetValueEx failed; code 5.
Access is denied
Click Retry to try again, ignore to proceed anyway, or abort to cancel.
Operating system: Vista Home Premium
Computer: Sony Vaio VGN-FZ470E
Antivirus: BitDefender
Any help with this would be appreciated. Thanks, Serge
