System.BadImageFormatException while connecting to DB2 from .Net

Question

I have DB2 server that I'm trying to connect from my machine, but I keep getting the below error when I start the application, before even start the connection

System.BadImageFormatException: 'Could not load file or assembly 'IBM.Data.DB2, Version=9.7.4.4, Culture=neutral, PublicKeyToken=7c307b91aa13d208' or one of its dependencies. An attempt was made to load a program with an incorrect format.'

please not that I don't have DB2 driver installed on my machine. but I refer to the below libraries in my application, which I got them from DB2 database server.

IBM.Data.DB2;
IBM.Data.DB2.Entity;
IBM.Data.Informix;

looks like you are missing some assemblies required for using your db2 provider client lib. you might wanna search what is missing and install the proper packages or runtimes. — Siavash Rostami

By getting to know what are your runtime assemblies. a simple google search can help with that. — Siavash Rostami

Those libraries need need a driver. You need to go into Admin tools and add an ODBC connection to the DB2 server. — jdweng

Normally the error message is caused by a 32/64 bit conflict.

Your program could be compiled in 64 bit (or any) and the drivers in 32 bit or the other way round.

Check the Configuration Manager and set the Platform to x86 or x64.
