WMP.dll is a file used by Windows Media Player to help process the various media formats on your system. Each time you play a media file on your PC, the wmp.dll file plays a vital role in being able to process all the data & sounds which the program needs to play. In short, this file is extremely important for your system, and if you're seeing errors caused by it, then you really need to be able to fix it to enable your PC to play back the media files you want to listen to / watch .
Errors with WMP.dll typically show in this format:
- The file wmp.dll has a version number of 9.0.0.3075 where 9.0.0.2980 was expected. Windows Media Player is not installed properly and must be reinstalled.
The reason for this error to show is actually all down to a confusion with the Windows Media Player program. The confusion is all down to the way this program has actually been updated, but has not recorded what version number it is now running. This means that whenever you use the media player, it's constantly conflicting with itself because it thinks it is a certain version, but it has files that say it's an earlier version than that. In order to be sure that you have a Windows Media Player program that functions correctly, you should look to use various methods to ensure that WMP is running at the same version across your entire PC.
The way to fix the WMP.dll error is to first use the Windows Media Player updater to ensure that all elements of this program are up to date. You can do this by using the "/ updateWMP" command in the DOS PROMPT Window – which will basically look at the "real" version of the media player, and then make all files associated with that program the same version. After you've done that, you should look to "re-register" the wmp.dll file on your system. Each DLL file is "registered" on Windows, allowing it to quickly find it. By unregistering the file, and then registering it again, you'll bring it back into line, allowing your computer to run the file it requires whenever it needs it. On top of that, it's also recommended that you use a "registry cleaner" program to scan through your PC and fix the various errors that are inside your system. These tools are great for fixing many DLL errors on the Windows system, and using one is recommended for cleaning up any problematic parts of the wmp.dll file that may be left on your system.
