  • Is this the 2.0 beta or the 1.6 released version? DId the problem just begin after OneCare has been running fine for any period of time or has this started happening after a new installation?

    If part of OneCare has crashed at boot, and then the error report is sent, you generally will not get a response. Does OneCare then start normally and fully function? Is the status of OneCare green?

    What operating system is this on and are there any other security software packages installed?

  • Stephen,  I had my OneCare running fine on 3 computers on a home Windows XP network for several months.  Then last month, the program on my laptop would show the Red status light but would not open.  I would get the same error code that the other guy did.  No other security software.  Ideas?

  • It can mean that .Net Framework is corrupt on your PC.

    To repair .Net Framework 2.0 on XP:

    Open Control Panel

    Select Add or Remove Programs

    Locate Microsoft .Net Framework 2.0

    Select the entry and when the installer launches, select Repair.

    Reboot when it completes.


    Alternatively, see this KB article:



    To remove a corrupt .Net Framework install, use this tool:



    The download of .Net Framework 2.0 can be found here:



    To repair .Net Framework 2.0 and 3.0 on Vista, see this blog entry:



    It can also be due to the date and time being incorrect on the PC or it can be due to a database problem within OneCare.

    Red OneCare system tray icon and error:

    "OneCare has encountered a problem and might not be protecting this PC"


    Check the date and time on your PC. If it is incorrect, the problem you encountered could happen.


    If the date and time are accurate, the permissions on the OneCare folder may need to be reset by using the following steps


      • Click Start->Run->Type “CMD(In Vista, type cmd in the search box, but don't hit enter and then right click command.exe and select and “Run as Administrator”)
      • Type    CACLS "C:\Program Files\Microsoft Windows OneCare Live" /t /g administrators:f
      • Type “Y” when prompted.
      • Restart the machine
