I cannot install juicebox-pro v1.4.4. The following message comes:
Sorry, an error has occurred
The application cannot be installed due to a certificate problem. The certificate does not match the inastaaled application certificate, does not support application upgrades, or is invalid. Please contact the application author.

I have tried removing my older version of juicebox, but to no avail...
Using the newest version of El Capitan 10.11.4 (today's version)
