The main error with the WMP.DLL file...

Often frustrated Windows Media Player users contact me to ask about this type of error message:

"Every time I try to open up Windows Media Player, the same message pops up, reads as follows:

The file wmp.dll has a version number of where was expected. Windows Media Player is not installed properly and must be reinstalled.

However, reinstalling Windows Media Player does nothing; I receive the same message when I try to open it up again."

Now whilst the version numbers may change.... If you get this error message on your computer, it is very easy to rectify the problem!

Simply go to the Start Menu and select Run

In the small box that opens up type in the following:

c:\windows\inf\unregmp2.exe /UpdateWMP

This should now clear up the "confusion" your computer was having with
version numbers of Windows Media Player.

Another not so common WMP.DLL issue

Another less common WMP.DLL error message I have come across is:


Every time I try to start a video, a message comes up
with "explorer has caused a problem in wmp.dll"


To rectify this issue you can re-register the wmp.dll file on your computer. To do this go to the Start Menu and select Run.

In the small box that opens up type in the following:

regsvr32 wmp.dll

WMP.DLL error on install of Windows Media Player 9, 10 and 11

When getting errors on installing WMP onto your computer it is excellent advice to FIRST check the setup file:


Then look for ANY lines that contain the entry:


An example may be:

ERROR: Dll Registration: Failed for file 'C:\WINDOWS\System32\wmp.dll'

Only then can you begin to isolate the problem.... Once you have the information you can post a request for help in the Windows Media Player newsgroups or type the error code into Google and see if that can provide you with a solution...


DVD Decoder for Windows Media Player?

Several major software companies have created a small piece of software called a "plugin" that you can purchase to make Windows Media Player play your DVDs.

(The reason they are not free is that a "royalty" has to be paid each time the DVD Decoder is installed on a PC, to the folks who own the MPEG-2 format - and no its not Microsoft!).

These are TWO main DVD "plug-ins" to chose from depending on your operating system.
