Yes i am seeing something similar on a Windows XP system. Patch had already been applied to the system but windows update notification prompted for the update again recently. Before applying the patch a second time, I checked the four files associated with the update found here: HKLM\SOFTWARE\Microsoft\Updates\Windows Media Player\wm320920\FileList The four files were present and matched what was in the registry FileList as far as version numbers go. Since the registry key and the files were already updated and i was being asked to patch once again, it would seem that there is a problem with the microsoft windows update catalog regarding this patch, though i haven't looked into this any further. Another issue (could be related) noticed with this patch is that it does not update the dllcache with the new files installed by the patch. For those of you not familiar with the purpose of the dllcache directory, it is the Windows File Protection file store. If a WFP protected file (many files within the systemroot dir are monitored by WFP) is deleted, renamed, corrupted, or whatever... WFP will take the copy it has within the dllcache (if it exists) and replace the broken or missing file automatically without ever prompting the user. A stroll through some of the other patch FileLists and you'll notice that most all of them will update the dllcache. Since the patched media player files are not installed into the dllcache directory, it's entirely possible that these files could get reverted at some point. I found an archived ntbugtraq post http://archives.neohapsis.com/archives/ntbugtraq/2002-q2/0072.html that mentions a similar issue with an earlier media player patch. The issue pointed out in the ntbugtraq post is really the same issue. What is occuring is that the earlier media player patch did not update the dllcache dir, and after running the System File Checker utility he noticed that the one of the patched files had been reverted to an earlier version. So for those of you out there that are using the SFC utility, you may want to look at your media player file versions and make sure they are the latest.

It still shows up as an update that needs to be installed. I have even tried to uninstall media player 7.1 and reinstall, then apply the patch and it does not work. This testing was done on 3 Windows 2000 machines and all with the same results. Roger Szulc __________________________________________________ Do You Yahoo!? Yahoo!
