How to fix MPLAB MCC Melody stuck at “handshaking content”

I updated my MPLAB from v5.45 to v6.2 recently, but when I tried to use my favorite MCC, it decided to turn into MCC Melody. Now, MCC Melody is basically just a better MCC Classic, but when I tried to open my new MCC Melody, it got stuck at “handshaking content,” and MPLAB was unresponsive. I fixed this error with the following steps:

  1. Turn off MPLAB through Task Manager
  2. Open MCC Content Manager (not MCC itself)
  3. Select the latest versions of all of the libraries you want (or optionally select specific versions – just make sure to have them)
    1. If you need only a specific device or content type, narrow down your search; however, I selected everything, and the download was almost immediate
  4. Click apply to download the selected libraries

I couldn’t find a solution to this error anywhere, so this is what I did to fix it. I’m not sure why this happened since it was a fresh installation of MPLAB, but I guess something didn’t get installed. I had the same error on a different installation, and this is how I fixed it there, too.

Microchip removed USB Framework Lite from the new MCC. I’m devastated.
