Defender\MpOav.dll Windows prevents facilities

When I tried to install the latest version of Silverlight, the error came as follows: it\ Program Files\Windows Defender\MpOav.dll prevents installation.

This error is also coming up with a few other facilities.

Hello cha11,

1. How are you trying to install Silverlight on your computer, it is from Windows update?

I suggest that you download the latest version of Silverlight from the Microsoft Download Center and you are trying to install it. Here is a link you can follow to download the latest version of Silverlight:

http://www.Microsoft.com/getSilverlight/get-started/install/default.aspx

I also suggest that you run an anti-virus on your computer, as it appears that there is a virus on your computer infection.

If you are still not able to install Silverlight, I suggest that you post your question in the Silverlight forum. You can follow the link below to ask your question:

  • A message to reinstall: MapI32.dll (Windows Search.exe) how to re - install.

    Original title: Reinstall: MapI32.dll (Windows Search.exe)

    After the installation of the update of Windows 8 for Windows XP, I get an error dialog box that indicates that I have to reinstall MapI32.dll (Windows Search.exe). How do I reinstall and why this happens?

    Thank you.

    E-mail address is removed from the privacy *.

    I can assure you with certainty at 100% none of Microsoft has 'expert' ideas Support Engineer will not replace a missing mapi32.dll file.

    These ideas are just more of their wild goose hunting to waste your time and get the points by posting useless ideas, not tested until they have links to the KB articles which will not work.

    First, nor fashion all safe or clean boot replaces a missing file.

    Second of all, the System File Checker don't know or don't care that file - and for the millionth time, I repeat is not what SFC/scannow, this isn't how it works and it's not what it is for.

    Everything that this alleged "expert" needs to do is re-create the problem (which takes about 10 seconds) and to apply their own prosecution goose to see that none of these ideas will help.

    Perhaps one day, these 'experts' will learn how XP works.

    If I were Microsoft, I'd be embarrassed and ashamed of these representatives (then I would lay off).

    If you mean that you see a message like this:

    WindowsSearch.exe - Unable to locate component
    This application has failed to start because the MAPI32.dll file not found.  Reinstalling the application may fix this problem.

    If the file is missing, it may have been quarantined (effectively removed) by your antimalware/antivirus application not specified on your unspecified brand system and model with unspecified XP version and unspecified Service Pack, but you can replace it.

    I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

    You can download it and when you do, place a copy of the file in these folders (assuming that Windows is installed on your C drive):

    c:\Windows\System32

    Here is the link to my SkyDrive and you can get the file you need here:

    https://SkyDrive.live.com/?CID=6a7e789cab1d6f39&ID=6A7E789CAB1D6F39! 311

    When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

    When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

    You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file named mapi32 when the name of the file should really be called mapi32.dll (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

    You then put the files downloaded to the appropriate on your system folder.

    That may not solve all your problems, but at least you will be spending this part and we can then fix the rest.

  • avfoundationcf.dll windows 7 error 126 with Itunes

    Original title: avfoundationcf.dll windows 7 error 126

    I think it's a question of ITunes but I tried everything with them.  I get "windows 7 error 126 avfoundationcf.dll" & Corefoundation.dll"not found - online, I see patches to repair Windows 7 - is this desirable?  If so, how?

    I think, I found a solution (it helped me):

    OK I GOT IT! with the help of reading the previous posts above.

    Here's what I did:

    1. run Add/Remove (Panel).

    2 uninstall all THE programs Apple (itunes says to start with itunes and quick time, Hello and then finally AMDS (cradle mobile apple). you may need to close the Add/Remove program and reopen it so that the amendments will not appear on the list.)

    3. RESTART/REBOOT YOUR COMPUTER!

    4. go to itunes.com, download the most recent version, save it on your desktop, RIGHT click the icon and select RUN AS ADMINISTRATOR.

    5. when itunes is finished installing, * DO NOT, I REPEAT DO NOT * click on end right now.

    6. connect your device (iphone, ipod) to the USB cord, you will see a popup window in the lower right... it's your computer, research and the installation of the device driver.

    7. once the driver is installed, you can click FINISH on the itunes Installer.

  • c:\windows\system32\vsinit.dll question prevents the activation of XP

    A malware attack left a mess on my machine and anit-virus tools cleaned most, but many services were lost. Advice on the web says to reload XP.  I did, but the activation step failed due to a problem with the license with c:\windows\system32\vsinit.dll.  The DLL is in place and apparently comes to ZoneAlarm, but most likely has been charged as part of another package (perhaps by malware?).  There are two registry entries that refer to c:\windows\system32\vsinit.dll.  My question is, can I change the registry references to c:\windows\system32\vsinit.dll and thus enable the XP activation process to proceed?

    The instance that is more suspect is

    HKEY_LOCAL_MACHINE-1-5-18\Components\913979572FD8B4D4989DEDA591E6AB3D

    If not, is there another solution to this problem, which is more suitable?

    Hi jimTheFlutist,

    Method 1

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP 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.

    See the link below to learn more about how to clean boot.

    How to configure Windows XP to start in a "clean boot" State

    http://support.Microsoft.com/kb/310353

    Reset the computer to start as usual

    When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

    (a) click Start, type msconfig in the search box and press ENTER.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

    Method 2

    If the previous step fails, then analyze and remove any malware or computer virus infections and check if that helps.

  • lgimcden.dll (windows xp)

    To start up I get the message next - window\lgimcden.dll module is not found. How can I fix it?

    Bill

    Looking for errors like this by doing a search on Google for the name of the file.  Usually, they turn up without success.

    When a search in no hits or suspicious hits result, the answer is usually that the file in question is linked to the malicious software and your anti-malware application has deleted or quarantined file, but left to the Windows registry entry that tries to start the malicious software when you start your computer.

    First of all, download, install, update and run full scans with two of these free analytical tools:

    MalwareBytes AntiMalware
    SUPERAntiSpyware

    Do not run the scans at the same time.  They can take some time, so start an and then go for a non computer chore for awhile.

    If the scans does not solve the problem (and they can't, because the actual malware file has already been processed), then download and run Autoruns.  Click on the "Connection" tab and look in the column 'Image path' for the dll named in your error message.  If it is not displayed in the connection tab, click the "all" tab and use the file > search tool.  A characteristic of the search of Autoruns tool is that you must move the selection under the element line "found" before you "Find Next."

    Once you find the line with the file in question, either "delete" or (if you want to be safer) uncheck the box.  The latter prevents the line running, but you can reactivate it later by removing the check mark.

Tried to do to reinstall win 7 x 32 bit disc no good. Don't know why but connected to the xbox 360 Wireless network adapter and it finally started and began to read the disc. Got straight to the point of failure weeks. Do not know with certainty if the adapter has helped who cares? Anyway had a read error so I went to windows defender after removing the adapter AND disc to analyze the error found in almost 90% of the said analysis "program cannot verify updates definition error 0 x 80004004.» Abandoned operation.
