SYMPTOMS

Cannot open filename. Please verify that the path and filename are correct and try again. (Error=80041001)

Cannot open filename. Please verify that the path and filename are correct and try again. (Error=80041002)

CAUSE

This is a problem that occurs only with packaged media. Packaged media is multimedia file that has been encrypted using Windows Media Rights Manager and can only be played by obtaining a valid license. There following two issues may cause this problem:

You have run the RegClean utility, which has removed registry keys necessary to play packaged content.

You may have an incorrect version of Drmclien.dll on your computer. This file is a system library necessary to play packaged content. If the version number of Drmclien.dll precedes version 1.00.00.3688, licenses acquired with it may not work.

WORKAROUND

If you have run RegClean, you need to uninstall and reinstall Windows Media Player.

If you are experiencing this problem and you have not run RegClean, you may have the incorrect version of Drmclien.dll on your computer, or you may have acquired a license with an incorrect version of Drmclien.dll. (Drmclien.dll may have been updated in the interim, but any licenses obtained with the incorrect version of the file continue to cause this error to occur). Uninstall and reinstall the Windows Media Player to ensure you have the latest version of Drmclien.dll. If the problem persists, you have to remove any existing license and key files from your computer. This directory (on Windows 95/98: c:\windows\all users\drm, on Windows NT: c:\winnt\profiles\all users\drm) contains files with .lic and .key extensions. These are the files that need to be removed.

Note: By default, license and key files are hidden system files. To remove these files, you must enable viewing hidden and system files. For more information on how to do this, see the following article in the Microsoft Knowledge Base:
