This addresses an issue for NAS or pre-2012 DVD/download products.
Generally when we run into this, the underlying issue is that Windows Media Player is unable to update the local DRM folder. The fix is to delete the contents of the DRM folder and then have Windows rebuild it:
NOTE: DO NOT delete the folder. Delete only the contents of the Folder. Deleting the Folder can make your DRM permanently unusable.
1.) Un-hide the DRM folder
a. Click Start, and then click My Computer.
b. On the Tools menu, click Folder Options, and then click the View tab. OR
In Windows 7, click Organize then 'Folder & search options' and then the View tab.
c. Check the "Show hidden files and folders" check box.
d. Un-check the "Hide protected operating system files" check box.
2.) Locate the DRM folder. Depending on your OS, the DRM folder is located as noted below;
- Windows 7 / Vista: C:\ProgramData\Microsoft\Windows\DRM
*Note: you may see a folder called DRM at C:\ProgramData\Microsoft\DRM. This is NOT the one you want !
- Microsoft Windows XP: C:\Documents and Settings\All Users\DRM
3.) After finding the Folder, please delete it's contents. DO NOT Delete the entire Folder. Only the Contents! (If you want to save the contents, create a new directory and copy the contents of the DRM folder to it.) If you receive a permissions error, Verify; that all browser windows are closed so the files are not in use and that you have sufficient permissions to clear this folder. As a last resort you may need to reboot into safe mode and try again. Instructions on booting into safe mode may be found here: http://support.microsoft.com/kb/315222
4.) Once the folder is empty, please try to play a video OR navigate to http://drmlicense.one.microsoft.com/Indivsite/en/indivit.asp?force=1 in Internet Explorer and attempt to apply the DRM CRL update located on this page. Either way, Windows Media Player will want to do a Security Update. Allow the update to complete - it should take less then 2 minutes.
This process resolves most of these DRM related issues.
One of our Members sent this MS KB article that includes a Windows 7 specific fix although using a different process from the one above. "You cannot play a Windows Media DRM protected file or a Zune DRM protected file on a computer that is preconfigured with Windows 7" http://support.microsoft.com/kb/976590
If the security component update will not complete the following was provided by one of our members and may be worth a shot if you're comfortable trying it for Windows versions prior to 7. In the registry; HKEY_LOCAL_MACHINE / SOFTWARE / Policies / Microsoft / WMDRM, Select DisableOnline and change the value from 1 to 0 then try the security component update again.
