The database files are present — so it is not a missing-file issue. This is important information:

Databases found:

• EngineScan.db — this is most likely the file containing the engine list that the "Select Engine" dialog needs to load
• NDMS.db — NDMS system database
• DiagAssistant\DiagAssist.db — diagnostic support database

So the issue is not missing databases, but rather that the software cannot read the database or that the database is empty.

Continue checking — run the following commands in cmd:

1. Check the database file size:
→ Post the result here. If the file is only a few KB or 0 bytes → the database is empty/corrupted.

2. Check the contents of EngineScan.db:

Download DB Browser for SQLite (free), then:

• Open the file C:\Doosan\DMS-5\EngineScan.db
• Check the "Browse Data" tab — verify whether the tables inside contain data or are empty
• Take a screenshot of the table list and the contents of the first table

3. Check whether the file JastecLogin.dll has been patched:
→ Compare its size with the original file in the archive. This file handles login authentication — if the patch did not modify this file, the software may still be trying to authenticate online and blocking the loading of the engine list.

4. Check the contents of the Patch folder:
(or the correct path to the extracted patch folder) → I need to know which files the patch contains — whether it only has DMS-5.exe or other files as well.

Post the results of the 4 commands here — I will determine the exact cause.

Everything works, no glitches. Thank you very much. The only thing missing is separate diagnostics for EDC7 Euro 3.4.5 engines. If you have it, please upload it......
