If you can manually access the file, try the right click and SEND TO command. If nothing else, you can put it on the desktop.
Apparently your sndcol32.exe file works. So, try typing in the RUJN sequence referenced in the KB.
"Click Start, and then click Run.
Copy and paste or type the following command in the Open box, and then click OK:
mmsys.cpl
Click to select the Place volume icon in the taskbar check box.
Click OK"
Why not just replace the sndcol32.exe file?
