So, I’m happy to report that I finally had success exporting a track as a WAV file!  Many thanks to John and everyone else here.

First, I ran EZ Drummer as an administrator.  I am running Windows 11, so there was no option for doing this in the context menu.  I had to select the program icon and then hit CTRL+Shift+Enter to run it as an administrator.  The first time I tried it I got the same error message.   But I also got a popup message from Avast, my antivirus program stating that it had blocked an app it saw as dangerous. I clicked on “allow the app.” and then tried it again.  Voila!  It worked.  Now, I’m thinking the problem MAY have been AVAST blocking the process and NOT the fact that it wasn’t being run as an administrator.  But either way, it doesn’t matter because it worked.

As a side note, for what it’s worth, the reason I want to do this is because I’m thinking of purchasing this Nux JTC Loop Pro looper/drum pattern player.  It has 256 slots to save “one shot” files. The files must be 24 bit 44.1K.  One shot files don’t loop.  They can actually be whole backing tracks with multiple instruments.  So, as a one-man-band, I am thinking about creating whole songs in EZ Drummer and then exporting them as 24bit WAV files that I can then import into the JTC Loop Pro via USB and have the potential to have up to 256 full-song backing tracks.  Initially I would probably just use this function for drums to play along with, but I could import the drum track into my DAW and create a full band backing track to use.
