Hi BEN AMOR as your account is new I'm not keen on clicking random Google drive links in case they're virus or Phishing links.  I'm sure you're legit and well intentioned but could you edit your question and paste your screenshots directly into your question as images are supported in the text area.  Thank you and we will see how we can help.

Hi BEN AMOR I have never seen this database load utility before I'm sorry, I've only ever used DBLOAD32.exe and loaded the sample data from SAMDATA:
 

Plus I've never installed into the Program Files directory for a Sage 300 deployment so I'm not sure what to advise.  I didn't even know .ini files for sample data were a thing.  Those files do look like Sage 300 ERP (at first I thought maybe you were using Sage 300 CRE (Construction).  Maybe this is the differences with a French localised version of Sage 300.  I'm not sure how to help...maybe someone else here?

What is the name of the exe that you are launching from the runtime folder? 

SampleDataLoader

I encountered this error using the file you mentioned before.

This is really starting to look like a job for a Sage 300 consultant, that said I will persist to see if we can get your SAMDATA loaded.  Could you please assist with:

1. What version and edition of Sage 300 is this?
2. Does your ODBC connection pass the connection test i.e. when you open C:\Windows\Syswow64\ODBCAD32.exe -> select System DSN tab -> open your Sage 300 DSN -> go through next/next/next using your SA SQL Auth credentials (just for now), do you get a succesful test result at the end i.e.:
   
3. Also make sure if using version 2022 or later that you select "Trust the Server Certificate" or set encryption to "Optional":
   
   
   
4. Try running your DBLoad again.

Cheers
