Interface Not Registered error when Visual Studio 2010 program runs on Win 7 32bit
<p>I wrote a simple WFA in C#, that runs like a charm on my win xp machine and on a win 7 64bit machine, but seems to crash every time on a win 7 32bit. I rally can't understand what is the problem, and why the program crashes only on taht machine. Do you have any idea?</p>

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

&lt;configuration&gt;
    &lt;system.windows.forms jitDebugging="true" /&gt;
&lt;/configuration&gt;

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
