Hi,

When I deploy the asp.net application on 64 bit OS mechine I am getting the following error.

The same application is running properly in 32 bit mechine.

Error :

You may have a dependency on an assembly that only exists for 32-bit or hasn't been properly installed in the GAC on your 64-bit machine.

Hi, a Visual Basic 2005 project was saved on a USB memory. Then it was copied to the hard disk. When trying to open the project from the hard disk, it is not possible to load some forms and this is the message that appears:

Errores al cargar el diseñador. Los errores se citan a continuación. Algunos errores se pueden corregir volviendo a generar el proyecto, otros puede que requieran cambios en el código.

When introducing again the USB memory, it's possible to work again from the hard disk, but when trying to remove the USB memory, it's not possible until you close the Visual Basic project because it says that the storage device is being used. So, it's possible to work from the hard disk only when the USB memory is inside, even when the whole project was copied and pasted from the USB to the hard disk. How can you make a project created in a USB memory to work independently on your hard disk without the necessity or dependency on the USB memory? Please help and write to webmaster@jaimemontoya.com is you get to find a solution. Bye.

Does anybody know the solution?

This occurs when a dll dependancy is missing. To solve the problem, our build guy had to remove all the dlls from the website and rebuild by putting them back one by one until the problem dll was found. The problem dll used external libraries that did not have all supporting dlls in the bin dir.

Hope this helps.

Excellent Answer...
