The command that you entered
 
mklink /j "Metronome" "C:\Cakewalk Content\SONAR X3 Producer\Metronome"
 
would created the junction in the current directory. In which directory did you issue the command?

The prompt began with
 
C:\Users\Studio Vheissu>
 
followed by the flashing cursor. Should I have changed this display first? If so, how? I'm only an intermediate when it comes to command line syntax (sorry). Thanks for your help so far.

You created the link in the wrong directory. You can safely delete that link. What version of SONAR do you have?

X3 now. I never had the problem before in any other Cakewalk version (I go back to Pro Audio days). How would I delete the link? Again I apologize for ignorance in this area.

This is an issue I encountered when I bought MC6 off Steam for $17.

Just like you would delete any file.
 
Rather than messing with just the metronome directory, you might be better off, reinitializing SONAR. While there is a copy of the audio metronome files in Cakewalk Content, there is another location that is the basis of your local copy used by the drop down in SONAR. Try this, Start SONAR with the CTRL+SHIFT keys pressed. This will re-personalize SONAR, copying a bunch of files including the metronome files into the correct location.

That worked. Thanks so much.

Good news. You are welcome. Much easier that messing around at the command line.

That worked. Thanks so much.

 
Hey, Vheissu.  I don't encounter a fellow Pynchon fan too often!

I just installed X3 upgrade from X2 and did not delete X2.  So far I love the program... but am really frustrated that Ive now spent almost my entire morning trying to make the metronome work.  I have no data in the drop down boxes in metronome preferences ( I believe X2 said "ping" or something similar).  I wouldn't have thought the metronome would've been the show stopper but it is.  I had the same problem in X1. 
 
I don't mean this to sound as sarcastic as it may sound, but without resorting to heroic measures like entering DOS commands or rebuilding the operating system... isn't there a layman's version of how to get the metronome to work?  ... its a metronome..
