How can I catch the exception so it doesn't break?

So I'm trying to build an executable. The project I'm running is building on X86.

When I build the project, everything seems fine and I get an executable. But the executable doesn't run. I get an error saying:

'child' is not a child control of this parent.

Followed by, Exception:

Class not registered (Exception from HRESULT: 0X80040154 (REGDB_E_CLASSNOTREG).

I made sure everything is X86 and I cleaned the solution and rebuilt. But I still get these errors. (I tried switching to X64 and Any PC and those options can't even located my DeviceBase.dll) When I started debugging, it took me straight to a specific function of the code.

protected override void Call(bool calling)
{            
    if (calling)
    {
        if (components != null)
        {
            components.Call();
        }                    
    }

    //This is where I get the exception saying
    //cannot access a called object
    base.Call(calling);
}

The Stack trace gives me something like this:

Message=Cannot access a disposed object.
Object name: 'Icon'.
ObjectName=Icon
Source=System.Drawing

The components starts off as null, and calling is initially false. How can I handle this exception in a proper manner? Any advice is appreciated.

Thanks for everyone's help. But I had to get device software specific files (.dlls) and set embed interop types to false. That did the trick.
