Hey there, let's troubleshoot this step by step to get that 3270 session option showing up! 🛠️

Double-check the plugin directory placement
A common pitfall here is the plugin folder location. If you're using the installed version of MobaXterm, plugins need to go into %APPDATA%\MobaXterm\plugins (you can paste this path into File Explorer to jump right there). For the portable version, it should be a plugins subfolder in the same directory as your MobaXterm.exe file—not just directly alongside the executable. Chances are you might have placed the .mxt3 file in the wrong spot.
Verify the plugin is loaded
Open MobaXterm, head to the top menu bar: Settings → Configuration, then switch to the Plugins tab. Look for X3270Suite in the list of installed plugins. If it's missing, the app didn't pick up the plugin—fix the directory path and restart MobaXterm properly.
Do a full restart of MobaXterm
Sometimes closing the main window isn't enough to fully shut down the app. Right-click the MobaXterm icon in your taskbar and select Exit, then relaunch it. This ensures the plugin gets loaded on a fresh start.
Check version compatibility
Make sure the X3270Suite plugin version matches your MobaXterm version. Older plugins might not work with newer MobaXterm releases, and vice versa. If you suspect this, grab the plugin version that corresponds to your MobaXterm build and reinstall it.
Try manually creating a 3270 session
If the plugin is loaded but still not showing up in the session list, you can create one manually: click Session → New session, then look for a 3270 option in the session types, or go to the Custom tab and run the command x3270 [your-host:port] to launch the session directly.
