I keep getting this message, I’ve uninstalled and reinstalled twice. same issue, don’t know what to do HELP
That means Windows is blocking the engine from starting or blocking the ports
Try doing a “clean install” using the steps provided here: MCEBuddy - Common Install, Uninstall and Start Up Issues
Then open the Control panel → Click on Services (or access it from the Task Manager if you’re using Windows 8.1 or 10), find the service MCEBuddy2x and click Start.
If the service has started then your firewall or antivirus is blocking the port (23332) used by the MCEBuddy service (engine) to communicate with the client (GUI).
I’m having this same issue, and I have tried multiple things to fix it. Tried uninstalling, trying reinstalling and even a clean install. Nothing is working. What else can I do?
EDIT; I even purchased the newer version 2.6.2 to install it and still not working.
Do you have an antivirus or firewall installed? They may be blocking the communication between the engine and the app.
Otherwise start the GUI app and click on Events and see what’s errors are logged in the system events.

I do have an antivirus installed and a firewall, but I have checked them and they seem to be ok. I even added it the firewall as an app exception with port 23332. But I’ll post the event logs here. Maybe they will help to figure out the issues.
EDIT:
Here are all my windows event logs from the 24 hours or so.
