I have a MC 26 master license that I’d like to use for installing JRiver on a raspberry pi 4 with 2G RAM (not the latest 4B model, but its immediate predecessor).  I’ve tried to follow the various guides available on the MC26 and MC27 pages, but so far no success.  I have been able to install the package, but when I try to launch the program from the desktop, it doesn’t launch.
I’m wondering if it’s a compatibility issue with Raspberry Pi OS, since I had it working previously under Buster.  One day I was fooling around with the memory settings on the pi, and it locked and wouldn’t boot.  Won’t do that again.  Had to reformat the SD card and start all over.  But after I updated the OS to prepare for the re-installation, I haven’t been able to get JRiver to work.  Is it a 32-bit vs 64-bit issue? I don’t know, but I can’t figure how to re-install.

Here are the instructions for MC26 and the RPi:

It's not a 32 vs 64 bit issue.

Only thing different is the code installing MC27, for MC26 use this:

Code: [Select]

wget -q "http://dist.jriver.com/mediacenter@jriver.com.gpg.key" -O- | sudo apt-key add
sudo wget http://dist.jriver.com/latest/mediacenter/mediacenter26.list -O /etc/apt/sources.list.d/mediacenter26.list
sudo apt-get update
sudo apt-get install mediacenter26

Thank you both for your replies.   I had tried following each one of those two to the letter, but neither worked.   Then I tried loading MC27, but no luck.   Maybe I’ve got a corrupt SD card, or one of the files got corrupted, and I need to start all over.   That’s why I posted.  If I’m the only one having a problem, the trouble must be with something I’m not getting quite right.

I also have had no issues with loading MC27 on a rpi4. You are correct that your SD card could be the problem.

I have issues with getting my NAS to mount on boot, but otherwise was able to install media center 27 just fine on my pi 4.

Besides the SD card, you might have some issues with a voltage drop when starting MC.
I have experienced some bad performance with JRiver (and other apps) when the voltage drops below 4.9 VDC (rPi 4).
I can even  reproduce it, by connecting a USB powered DAC to the USB port.
The pi will boot, load the desktop and shows the notification on the low voltage ratings. When this notification is on, the Pi seems to be in a survival mode. MC won't start, Wifi and BT menu fails to load.

So replace the SD, and make sure the voltage to the Pi is ok.

A quick update: I reformatted the SD card, reloaded everything from scratch, and it’s fixed!  All is working correctly.
Thank you everybody.
