RomRaider

yes, it was in normal mode, then changed to debug and trace mode as attached

Even with the extra logging there is no information to explain why it can not find your J2534 devices.
They should be listed right after this line in the log:
INFO [Query Manager] - J2534 Library names loaded from file: ./customize/j2534Libraries.properties

It should list the DLL filename for each J2534 vendor in your Registry. This is the code that does that.

You could try adding the DLL to the properties file.
Update the windows= line in the file:
"C:\Program Files (x86)\RomRaider\customize\j2534Libraries.properties"
to be:
windows=C:\\WINDOWS\\SysWOW64\\op20pt32.dll

hi, I did below;

Update the windows= line in the file:
"C:\Program Files (x86)\RomRaider\customize\j2534Libraries.properties"
to be:
windows=C:\\WINDOWS\\SysWOW64\\op20pt32.dll

here log file, not connected

You can see in the log that your change is noted:
22:34:31,501 INFO [Query Manager] - Trying new J2534/ÝSO9141 connection: Windows J2534 OP2 WinUSB

But it still does not load the DLL. Is this real or fake Openport 2.0?

The other item that is odd is the protocol name ÝSO9141, it should be ISO9141, I'm not sure why the first letter is different. There should be no translation to ISO numbers.

Hi. It is oem original tactrix openport 2.0 adapter. Mayne about settings of language or else? Thanks

If it is language related, I'd uninstall everything including the Openport 2 drivers, set the language to en_US and install it all again. If that works then switch the language back and test if it all still works.

hi, great stepup, after changing ssytem language, it doesnt ask comport anymore, try to connect now, but even select any parameters, still not connected as attached log file..

Not sure what language you used, but it still does not enumerate the J2534 libraries from your Registry. Plus the log shows an odd spelling of ISO.
INFO [Query Manager] - Trying new J2534/?SO9141 connection: Windows J2534 OP2 WinUSB

DONE ! I achieved this through blood, sweat, tears, and sheer determination

Here sharing final stages with thanks to Chatgpt..

CLEAR AND DEFINITIVE SOLUTION (IN ORDER OF IMPORTANCE)
PLACE THE ECU DEFINITION FILE IN THE CORRECT LOCATION
omRaider cannot find this file:
C:\Program Files\Romraider\ecu_defs.xml
What you need to do (the cleanest way):
Place the ecu_defs.xml file here:
C:\RomRaider\ecu_defs.xml
Open RomRaider as Admin
Settings → ECU Definitions
Manually set the path to:
C:\RomRaider\ecu_defs.xml
OK → Close RomRaider → Open it again
Nothing will be fixed without this step.
100% SOLUTION – CLEAR IMPLEMENTATION SEQUENCE
CLOSE RomRaider
It must be completely closed.
MANUALLY EDITING SETTINGS.XML (THE MOST IMPORTANT STEP)
File:
C:\Users\SALCI\.RomRaider\settings.xml
Open this with Notepad++ / Notepad.
FIND THE FOLLOWING BLOCK
You will see something similar to this (names may be slightly different):
<logger>
<connectionType>serial</connectionType>
<serialPort></serialPort>
<baudRate>4800</baudRate>
</logger>
CONVERT TO THIS (EXACTLY):
<logger>
<connectionType>j2534</connectionType>
<j2534Device>OpenPort 2.0</j2534Device>
<autoDetect>false</autoDetect>
</logger>
Delete all lines containing serial, com, baud, and port.
Save → Exit.
100% WORKING FIX (EXACTLY AS SHOWN)
RomRaider must be OFF
COMPLETELY CHANGE THIS BLOCK in settings.xml
DELETE THE FOLLOWING (entirely):
<serial port="" refresh="false"/>
<protocol name="SSM" transport="ISO9141" module="ECU" fastpoll="true" library=""/>
REPLACE IT WITH THE FOLLOWING:
<j2534 device="OpenPort 2.0"/>
<protocol name="SSM" transport="J2534" module="ECU" fastpoll="true" library=""/>
Make sure all characters, spaces, and capitalization are the same.
BLOCK FINAL STATUS (EXAMPLE)
Your <logger> block should look like this:
<logger locale="en_US">
<autoConnectOnStartup value="false"/>
<j2534 device="OpenPort 2.0"/>
<protocol name="SSM" transport="J2534" module="ECU" fastpoll="true" library=""/>
<maximized value="false"/>
<size x="645" y="1000" divider="400"/>
<location x="101" y="44"/>
<tabs selected="2" showlist="true"/>
<definition path="C:\RomRaider\logger_METRIC_EN_v370.xml"/>
<profile path="C:\Users\SALCI\Desktop\ss.xml"/>
<filelogging path="C:\Users\SALCI\Desktop" switchid="S20" active="false" absolutetimestamp="true"/>
<debug level="debug"/>
<plugins>
<plugin id="com.romraider.logger.external.phidget.interfacekit.plugin.IntfKitDataSource" port="HID USB"/>
</plugins>
</logger>
SAVE → EXIT → OPEN ROMRAIDER AS ADMIN
FINAL CHECK (1 FILE, 1 LINE)
Make sure the following is present in C:\RomRaider\customize\j2534Libraries.properties:
OpenPort 2.0=op20pt32.dll
100% SOLUTION – FIX THIS FILE (1 MINUTE)
OPEN the file
C:\RomRaider\customize\j2534Libraries.properties
Open with Notepad / Notepad++.
CHANGE THE LINE windows= EXACTLY
Existing:
windows=
CHANGE TO:
windows=op20pt32.dll
That's all
I don't want you to write the path or change the name.
DLL CHECK (VERY IMPORTANT)
This file must be here:
C:\RomRaider\lib\windows\op20pt32.dll
If it's not there:
Copy it from C:\Program Files (x86)\EcuFlash\
Copy it to RomRaider (don't move it)
Now, the only thing left is:
To see in the log that RomRaider actually entered the J2534 path.
FINAL CHECKS (1 MINUTE)
CONFIRM DLL LOCATION (IMPORTANT)
Is this file definitely here? (I want you to check manually)
C:\RomRaider\lib\windows\op20pt32.dll
If it's not here, it won't work.
Note: If it's in Program Files (x86)\EcuFlash\
→ copy and paste into RomRaider
FINAL AND CLEAR STEPS
j2534Libraries.properties (FINAL VERSION)
The file should be located exactly here:
C:\RomRaider\customize\j2534Libraries.properties
Its content should be exactly like this (no spaces, leave a comment, it doesn't matter):
windows=op20pt32.dll
linux=j2534.so ; /usr/local/lib/j2534.so ; j2534.dylib ; /usr/local/lib/j2534.dylib

Save → Close.
RESETTING THE OLD SERIAL SETTING (VERY IMPORTANT)
RomRaider keeps asking for the serial because the old setting is still there.
Go to:
C:\Users\SALCI\.RomRaider\
Do not delete the contents, only:
settings.xml
delete or rename the file:
settings.xml.bak
RomRaider will rebuild with clean J2534 settings when it starts.

That seems like alot of work to basically say "I moved the op20pt32.dll from the default installation directory to: <here>"

Simpler: delete the settings.xml file
If you need to move/copy the op20pt32.dll to C:\Program Files (x86)\RomRaider\lib\windows\ then do so and update the C:\Program Files (x86)RomRaider\customize\j2534Libraries.properties file with the entry:
windows=op20pt32.dll

When you restart RomRaider just reconfigure your defs and log locations in Settings.

It's easy to comment after seeing the solution, of course

It is exactly what I described in post viewtopic.php?p=172197#p172197
Assuming you have installed RomRiader and EcuFlash in the default locations.
If not then you will need to adjust the paths to where you did install these programs.

And, do not do anything using "Run as Administrator" as this just makes the mess worst.
