I have my friend's Dell Laptop with me to see if I can fix the non-playing audio. At system boot, we get an error on AVRT.dll. See: http://i242.photobucket.com/albums/ff2/whftherb/Vista3.png
This message appears when attempting to launch WMP off the start menu. See: http://i242.photobucket.com/albums/ff2/whftherb/Vista4.png
WMP never runs.
I've renamed that 2008 version and replaced with a 2006 version found on the net. Same problem. I've preserved the old (orig) copy of the .dll.
I've attempted to reinstall WMP with a fresh d/l from MS and I get this: http://i242.photobucket.com/albums/ff2/whftherb/Vista8.png
I've attempted to uninstall the corrupt WMP and all I see is it's missing and cannot therefore uninstall it.
I've looked at the services.msc panels and I see that a dependency service of the Windows Audio Service called Multimedia Class Serivce cannot be started.
So, I'm stuck now as to what to do. Can someone please work with me to fix this thing?
