No sorry I don't, rather than dloading and installing wmp everytime, you could dl the file, quartz.dll, and replace into c:\windows\system32. For the file click here
It may work, but you may have to do as before.
Another user, on a diff forum had a simialr prob, but on windows 2000 (I'm assuming you're using XP);
"Eventually I was able to do it by killing
the "WMDM PMSP Service" while I installed the update (on my w2k machine, Control Panel > Administrative Tools > Services > Find and
Kill "WMDM PMSP Service")."
Hope this helps.
