"Invalid Operating System" error when you try to load McAfee

I try to load the McAfee virus scan, but I get an error message "Invalid Operating System".

OS is XP Pro comes with the system and the current version is 5.1 service pack 3. It would not have automatically updated from Microsoft if the OS was not legal

Hello

·        This only happens when you install McAfee virus or with the entire application?

·        How you try to install McAfee on the system from the internet explore or a disc?

·        Were you able to install McAfee before on the system?

·        What is the exact error that you are experiencing when you try to install a program?

I suggest to install the application in clean boot mode and check if you are able to install the program or not.

  • Loading error when you try to load the Halo 2 "files are missing or damaged in the installation directory. A few important files required to run this game are missing from the installation directory.

    Original title: load error when you try to load Halo 2

    People at Microsoft, I have a problem trying to load Halo 2 on my dv7 Paviliaon with Vista and the 2.8 GB Intel Centrino 2 processor. When I try and load the game, I get and error stating: "the files are missing or damaged in the installation directory. A few important files required to run this game are missing from the installation directory. "It bothered me for several reasons. One: the disc that I use is an original disc out of the box so hsould have no problem. Two: the game has been loaded previously on the same computer without apparent problem at the time. It has been deleted (don't remember why) and when I tried to reinstall, the error came. Three: I did as recommended and updated all programs and drivers, nothing works. So my question is, how do I reinstall Halo 2 and what this problem will arise if I decide to buy and load Halo 3?

    Thank you for your time in advance.

  • Setup error when you try to load LR 6

    I hope you can help me here.

    I work with Photo Shop for almost 15 years and LR since it came out.  In my wisdom

    (ha - ha) I decided for me LR 6 to give me a clean start... not the most organized person around.

    The latest version of LR is 4.4, well I don't have 5 on another computer but that you have not used to it... by

    the time I got to 4 I new where most things were and how to get to my files, so 4.4 LR is just

    my comfort spot.

    I'm a hold out for CC versions... but not in the budget, and on a fixed income, etc.  So I thought that I had

    Get 6 until the only thing left was the CC versions.

    Now that I have this beautiful LR 6 here I can't install it.  I tried 3 times and get a message that there is

    something doesn't work is not with the installation program.  I should also mention that I work on 10 to win.  Yes, I did

    what I thought was a good amount of research before buying 6 LR and decided to go there.

    You can offer me some suggestions?

    Have you tried clicking the button ignore?

    Hello

    What is the exact error message received when the problem occurs?

    Methood 1:

    Auditor of file system (CFS) scan to fix all of the corrupted system files. To do this, follow the steps in the following link:

    How to use the System File Checker tool to fix the system files missing or corrupted on Windows Vista or Windows 7

    http://support.Microsoft.com/kb/929833 

    Method 2:

    You can start Windows Vista by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    I suggest to put the computer in a clean boot state, and check if the problem persists, see the link:
    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7
    http://support.Microsoft.com/kb/929135
    Note: See step 7; Reset the computer to start as usual after troubleshooting is performed.

    Method 3:

    You can temporarily disable the security software and check if the problem occurs. Check out the following link to do the same thing:

    http://Windows.Microsoft.com/en-GB/Windows-Vista/disable-antivirus-software

    Warning: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    I hope this helps! Let us know if you need more assistance.

    I have redownloaded a game that has been previously loaded on my computer, now I get this error when you try to play the game "Memory Access Violation".

    Your sound card that is more than adequate.
    If the game was previously installed and worked fine then maybe it is not been completely uninstalled.

    Then restart and reinstall the game.

    Alternatively, you can try to install in compatibility mode. If the program is not compatible, then you try to install and run the program in compatibility mode.
    Use the following steps:
