Restoring the Windows Media Player plugin
1. If any of these entries are not present, look for the files in the Windows Media Player directory (usually C:\Program Files\Windows Media Player), and if you find them copy then to the Firefox plugins directory (usually C:\Program Files\Mozilla Firefox\plugins). Then repeat the previous step and check the files are all there.
2. If some of the files are still missing, you can download the individual files from dlldump.com:
* npdsplay.dll:
http://www.dlldump.com/download-dll-files_new.php/dllfiles/N/npdsplay.dll/3.0.2.629/download.html (this is the updated version)
* npwmsdrm.dll:
http://www.dlldump.com/download-dll-files_new.php/dllfiles/N/npwmsdrm.dll/9.00.00.3250/download.html
* npdrmv2.dll:
http://www.dlldump.com/download-dll-files_new.php/dllfiles/N/npdrmv2.dll/9.00.00.32508/download.html
Download them to the Windows Media Player directory (usually C:\Program Files\Windows Media Player) and then restart Firefox.
3. If the plug-in files still do not appear, try copying them to the Firefox plugins directory (usually C:\Program Files\Mozilla Firefox\plugins).
4. Special versions of Windows XP:
* If you use Windows XP Home N or Windows XP Pro N, see Issue 7 in the following section (Configuring/Troubleshooting the Windows Media Player plugin).
* If you use Windows XP Media Centre Edition, see Issue 12 in the following section (Configuring/Troubleshooting the Windows Media Player plugin).
If the plugin files are present but not functioning:
* Install this update from Microsoft:
http://www.microsoft.com/windows/windowsmedia/player/version64/plugin.aspx
It installs the plug-ins plus some other files.
* Download the thee plug-in files from dlldump.com and place them in Firefox's plug-ins folder (as mentioned above) - this is necessary because the plug-in installer from Microsoft contains older versions of the files, which have un-patched security holes.
