If you have several older versions of Harmony installed, it is possible that some of their shortcuts launch the wrong of Harmony. This is because, prior to Harmony 15.0, desktop shortcuts created for Harmony would not point to the full path of applications, so they launched the version of the application in the $PATH environment variable.
A script has been made to fix this issue. It will go through every installation of Harmony in the default installation location and create shortcuts for them with the proper configuration.
In a terminal, go to the directory where you downloaded the script.
$ cd <download directory>
Add execution privileges to the script.
$ chmod +x fix_harmony_shortcuts
Run the script with elevated privileges:
$ sudo ./fix_harmony_shortcuts
- Read the confirmation prompt, then type yes and press enter.
