Solution3. Copy the missing DLL file from another computer.

If the two solutions above don’t work, you can copy the dynamic link library that required by the applications from another machine. If you use Windows 7 X64 N, you can copy the file from C:\Windows\SysWOW64\ on another computer that had Windows 7 X64 with Windows Media Player installed to the same directory on the computer with the N version. If it is a 32 bit application, you need to copy files matching the same description from (and to) the folder C:\Windows\System32\.

Solution4. Fix registry errors.

Windows registry plays an important role on your computer. The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components and for applications running on the platform that have opted to use the registry. The kernel, device drivers, services, SAM, user interface and third party applications can all make use of the registry. The registry also provides a means to access counters for profiling system performance. Windows requires the values to remember how to load the programs correctly. If the registry entries get damaged and become invalid, Windows will fail to load the programs and then the errors occur. It is possible that wmvcore.dll not found error is caused by the registry errors.

To resolve the problem, you need to scan and fix the Windows registry. But it is a complicated and risky process to modify the system registry manually. So we strongly recommend you to download and install a professional registry cleaner tool to fix wmvcore.dll error quickly and safely.
