       I am using our wrapper on 64 bit vista but its not working giving exception for interop. Even though i build my solution as x86 the error is the same . So can u tell me what could be the possible error or in case u want my projectcode how can i send it to u?

  • Are you able to run the same program on a 32-bit OS?
  • What is the error you're getting?

Hello dblock,

                        yes i am able thr same program on 32 bit vista, the following is the simple source code  and the exception




using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Vestris.VMWareLib;

namespace Vertis
    class Program
        static void Main(string[] args)

                Console.WriteLine("Now we try to power on the VMWare...\n");

                VMWareVirtualHost virtualHost = new VMWareVirtualHost();
                // connect to a local (VMWare Workstation) virtual machine
                // open an existing virtual machine
                VMWareVirtualMachine virtualMachine = virtualHost.Open(@"e:\smoketest\winxp\windows xp professional en.vmx");
                // power on this virtual machine


              Console.WriteLine ( "The  VM is powered on...");

            catch (Exception e)
                string s = "The VM failed to power on because.....  ";
                Console.WriteLine(s + e.ToString());





Now we try to power on the VMWare...

The VM failed to power on because.....  System.TypeInitializationException: The
type initializer for 'Vestris.VMWareLib.VMWareInterop' threw an exception. --->
System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM cla

it seems that there its a COM->.net exception but the same wrapper works fine on 32 bit vista.

This just says that VixCOM is not registered. I would uninstall VixCOM (I assume you did install it :)) and reinstall it, then if the problem persists I'd ask why this happens specifically on a 64-bit system on the VixCOM forum.

Someone else ran into the same problem and found a solution. Make sure your program targets the x86 CPU and is not Any CPU (the default).
