    Post WMVCore.dll is missing in Windows 7



    I have upgraded to Windows 7 Enterprise on my Dell XPS laptop. Now, webcam, built-in with Dell laptop, will not work. When I try to open the Webcam Manager Application, it gives the error message as "WMVCore.dll is missing". So, can anyone tell me the fix for this? Please.

    Default

    Go to the below link and download the WMVCore.dll file:

    wmvcore.dll free download - DLL-files.com

    OR

    wmvcore.dll download - free dll files

    Then, place the WMVCore.dll file in C:\Windows\System32\. Then, reboot your system for changes to take effect.

    If still doesn't work, then open Elevated Command Prompt and run the below command:

    regsvr32 wmvcore.dll

    When you hit Enter, it will register the dll in Windows. Then, try to open Webcam Manager application.

    Default fixed similar problem

    Cyberlink PowerDVD player would not play on Windows 7 X64 N for me. N version has no Windows Media player installed with it. There is a link to download the Windows6.1-KB968211-x64-RefreshPkg.msu from microsoft, and I am sure that would have solved the problem, but it refused to install on my computer.

    The above did not work, those were the wrong DLL's.

    I copied all the files matching this description "WM*.DLL", where the file names were all caps, from C:\Windows\SysWOW64\ on a another computer that had Windows 7 X64 with Windows Media Player installed to the same directory on the computer with the N version. Then PowerDVD worked great.

    I assume that if PowerDVD had been a 64 bit application rather than a 32 bit application, I would have needed to copy files matching the same description from (and to) the folder C:\Windows\System32\.

    When copying, of course, I told windows to skip copying any files already present (and some were).

    I think there are probably a number of applications that rely on these DLL's.

    (Shame on microsoft for making an end run around the EU decision to make the tiniest effort to keep them from unfair trade practices.)
