I am starting my program from release folder. On my Windows 7 64-bit machine it is working.

In virtual machine Windows 7 32-bit it is working.

On third machine with Windows 7 64-bit it is not working.

On every machine I have installed .NET Framework 4, my project use .NET Framework 3.5 because I use SQLite database, and SQLite dll as I understand need for project to be .NET Framework 3.5.

I am using Visual Studio 2010 Express edition, SQLite database.

Here is error from third computer:

The Common Language Runtime from version 3.0 onward uses a different method to load a mixed-mode assembly (one containing both managed and native code) like SQLite. Since SQLite was built against the .NET Framework 2.0, we have to specifically tell the CLR to use the old 2.0 way of loading mixed-mode assemblies:

Add (or update) app.config in your project:

<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
  </startup>
</configuration>

In release folder there is no System.Data.SQLite.DLL, that was problem. Now when i copy it everything is working.
