Hello,

I am stuck in the following exception.

Could not load file or assembly 'RChilli, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.

This is a desktop application and it was working fine for last few months. Recently I have upgraded my PC to a 64 bit one, and since then I am getting this exception. Can someone help me to fix this?

Thanks for your time....

Regards
Sebastian

The assembly you're referencing was probably compiled only for x86 (not for x64 or 'Any CPU').
You can either try to find x64 version of assembly, or you can compile your application explicitly for x86 (in VS: Project properties -> Build tab -> Platform target)

In that case, will the application work in a 64 bit machine? I think no.

Hi,
You are building some of the projects in x64 and some in either x86 or Any CPU inside one solution.

Right click on the Solution, Select the Configuration manager from the context menu. Set all projects target platform to x86and re build again.

It is set to "Any CPU" already.

Have you made sure that all the projects involved are set to the same target and have you clean the binaries before rebuild?

yes

Then you are using a dll that is build for x64. you need to check all your references target platform are correct.

Have you tried with changing the target to x86?
