Cause: Copy protection. MEDOC expected to find a file on drive A: or a specific volume label.
Fix: In your C:\MEDOC folder, create an empty file named MEDOC.DSK or use a crack from PLCforum that patches MEDOC.EXE to ignore the floppy check.
Edit the DOSBox configuration file (dosbox-0.74.conf). Add these lines at the bottom:
[mitsubishi]
mount c c:\MEDOC
c:
SET BLASTER=A220 I5 D1
MEDOC.EXE
This auto-mounts your MEDOC folder and launches the software.
Do not download from random EXE files. Instead, use these community-vetted sources:

Look for threads from 2023-2024. | | MrPLC.com (Downloads) | Very High | None | Legacy member area.

Contains verified .IMG files. | | GitHub (search 'medoc24') | Medium | Low | Some users host DOSBox configurations. Check the code. |
To connect to an actual MELSEC PLC (e.g., via a USB-to-RS422 adapter), you must map a virtual COM port. In dosbox.conf:
[serial]
serial1=directserial realport:COM3
(Replace COM3 with your USB adapter’s COM port number). melsec medoc 24 download hot

While the demand is "hot," the method of acquisition carries risk. Because Medoc is technically abandonware—unsupported by Mitsubishi Electric—users searching for downloads are often navigating unsafe waters.
Official support channels no longer distribute the media, pushing engineers toward third-party file-hosting sites, forums, and peer-to-peer shares. This introduces the risk of corrupted files, malware, or modified binaries.
The recommendation for modern engineers is clear: If you are searching for Medoc 2.4, you are likely in a bind. While the download solves the immediate problem, the long-term solution is migration. The "hot" download should be treated as a bandage—used to extract the logic from a legacy machine—before migrating that code into a modern GX Works environment and, eventually, planning for a hardware upgrade.
