You might have faced the problem, when you try to run Windows Media Player. An error dialog box appears “Windows Media Player is not installed properly and must be reinstalled.”
Literally it happens due to mismatch version of some core Windows Media Player files. Following reasons may cause the problem like this-
- Windows Updates might have failed to installed Windows Media Player updates.
- You might have patched Windows Media Player files like wmplayer.exe, wmp.dll and so on.
The error messages may differ, but primarily it state
Windows Media Player is not installed properly and must be reinstalled. Do you want to reinstall from Microsoft website?
By following guide, you can also get rid of following errors-
“The file wmp.dll has a version 12.0.XXXX.YYYY where 12.0.AAAA.BBBB was expected. Windows media player is not properly installed and must be reinstalled. Do you want to reinstall from Microsoft website?”
“The file wmplayer.exe has a version 12.0.XXXX.YYYY where 12.0.AAAA.BBBB was expected. Windows media player is not properly installed and must be reinstalled. Do you want to reinstall from Microsoft website?”
“The file wmploc.dll has a version 12.0.XXXX.YYYY where 12.0.AAAA.BBBB was expected. Windows media player is not properly installed and must be reinstalled. Do you want to reinstall from Microsoft website?”
The major version of Windows Media Player may differ as per your Windows and Windows Media Player, for case it is 12

1. I receive this message:
“Windows Media Player is not installed properly. Reinstall the Player.”
when WMP11 opens DRM protected videos as well as when trying to start WMP DRM individualization process at Microsoft secure server:
http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp
2. The problem appeared after System restore to a previous restore point, made a day earlier, when WMP11 played DRM protected videos without problems.
3. The above solution did not work as such a file “unregmp2.exe” does not exist on my C:\ drive.
4. Other solutions ?
Thanks
unregmp2.exe is located in C:\Windows\System32 folder. So move to that folder and execute the given command. Like:
C:\Windows\System32>unregmp2.exe /UPDATEWMP
Sorry, I run Windows XP. On Windows XP the resolution is:
Start -> Run -> Type in: %SystemRoot%\inf\unregmp2.exe /UpdateWMP -> OK
Besides, I found a solution to my problem:
1. Uninstall Windows Media Player 11 and Restart.
2. Uninstall Windows Media Format 11 Runtime and Restart.
3. Reset existing DRM License Key by deleting the contents (hidden) of DRM Folder:
C:\Documents and Settings\All Users\DRM\
4. Install Windows Media Player 11.
5. Go to Microsoft secure server for WMP DRM individualization.
Thanks.
1. First, please delte the DRM folder on your computer. Depending on your OS, it can be found in different locations:
* Windows 2000 and XP: C:\Documents and Settings\All Users\DRM
* Windows 98: C:\Windows\All Users\DRM
* Windows Millennium Edition: C:\Windows\DRM
If you cannot find the folder, it may be ‘hidden’. Please use the following steps to view hidden files and folders.
* In Windows Explorer go to Tools > Folder Options > View
* Under ‘Hidden files and folders’ heading, make the following changes:
o Select ‘Show Hidden Files and Folders’
o Un-check ‘Hide Protected Operating System Files’
* Click the button ‘Apply to All Folders’. This will ensure the changes affect all folders on the system.
