First, I tried to set the default “Open with” configuration to WaveLab in the Get Info window. The system, initially, did not present me with WaveLab as an option to do so, i.e., the system didn’t know if it was possible to open the file or not.
I changed the selection options to allow any application to open the file. And still, after executing the External Tools menu options, the sample program was still greyed out.
Then I typed in the path and file name as per your suggestion and, after trying to run it, received the message the “The file was not able to be opened successfully; please check its definition.”
