Hi SRINIVASAK KANNAN,

One of the most important changes between previous versions of Windows and Windows Vista has been a passage from a file INF described OS to modularity.  A component of Windows is one or more binaries, a catalog file and an XML file that describes all the things on the way in which the files must be installed. Files must have keys associated with registry and services for the kind security permissions.  Components are grouped into logical units, and these units are used to build the different editions of Windows.

    Apparently, by mistake I deleted this program. Don't have any idea how to restore, HELP!

    This message comes to you NVIDIA video driver software that loads whenever your system is restarted.

    It's broken, but you can fix it.

    I suggest you just reinstalling the NVIDIA drivers as follows:

    The best way to reinstall the NVIDIA software is to visit NVIDIA support web page and let your system and recommend the best software for your system or that you get the right version of the software on their web page and download the latest package of video driver for your system software and install it yourself.

    If you have already installed the correct drivers NVIDIA said page, then you should download the drivers anyway and reinstall them yourself.

    It is recommended to run the scan NVIDIA with Internet Explorer.

    Here is the link to the support page NVIDIA for the scan:

    http://www.nvidia.com/download/Prescan.aspx?lang=en-us

    Read the instructions, and then click the GRAPHICS DRIVERS button to start the scan.

    Let online to take a look at your video system scanner them and see what he suggests for drivers and consider their analysis if they offer a new pilot.

    If following their indications do not straighten things, then follow these steps:

    When you have the time, I could do that too:

    Perform scans for malware, and then fix any problems:

    Fill in the blank: my system worked well until: _.

    Did the problem to the top after show installed new software and if so, what software?

    You have recently installed any type of remote control software?

    Now to fix it depends on how you are fixed to the boot media, since you'll have to start on something.

    We know that XP likes to keep the backup copies of critical system files in this folder:

    c:\Windows\System32\dllcache

    Knowing this, start in Recovery Console XP using your genuine XP bootable installation CD or if you have a genuine XP bootable installation CD, you can make one (no XP media required).  If you don't know what type of bootable media, you, do a CD of bootable XP Recovery Console and do not forget.

    If Yes, you want and are not in possession of a genuine XP bootable installation CD or a CD from Recovery Console XP bootable, the instructions to create a bootable XP Recovery CD of Console can / will be provided before any questioning begins.

    You can replace the missing file or suspect the XP Recovery Console by entering the following command:

    Copy c:\windows\system32\dllcache\odbcint.dll c:\windows\system32

    Answered in the affirmative if invited to replace the existing file and then you should see a message that 1 file (s) has been copied.

    If you get some type of a file not found message, the file is easily replaced using other methods.

    Remove the CD and type "exit" at the Recovery Console prompt to restart the system.

    Do, or do not. There is no test.

    Hello

    It seems that there are a few system files that have trouble.  One of them being mstsc.exe, I wish you find spyware or infection by the virus first, before you try the next step.  Please see the sticky thread in the security forum.  MVP offers some good advice how to remove these problems.

    If everything is clean, we will try a repair installation to replace the problem files and also to ensure that other system files are good.

    The 'repair' installation (upgrade on-site) will not affect your installed programs or data.  Just make sure that you are already connected to your computer when you start the installation.  Do not boot from the DVD.

    If the installation does not start automatically when you insert the DVD, run setup.exe from your DVD player.

    • When the Setup program starts and the install now screen, click install now.
    • Note When you receive the important Get updates for installation message, click go online.
    • Click upgrade when the which type of installation you want? appears
