通过C＃程序Windows 7以编程方式启动vm“ Windows XP Mode”

Question

Ok, so I'm having an issue starting the the Windows XP mode VM through ac# program. The command I'm using is vmwindow -file "absolute path to vmcx file " , but the problem is that the command does not work with the cmd prompt that my program kicks off. So, it's very weird. I can go to command prompt on my computer and run this command on my computer and it works, but if i have the same command on my c# program, the command prompt that pops up tells me the "vmwindow" is not a recognized command. I even looked at the paths of each of the command prompts and they're different, but they still both contain "C:\\Windows\\system32\\" which is where vmwindow.exe exists. So, I navigate on the command prompt window that my program populated and the file "vmwindow.exe" is not there, but if I open a command prompt window from my computer and navigate to that folder, it exists there. I can't think of anything else as I already made sure they're both running in administrator mode, and also i tried starting a bat file which contained that command instead of running the command directly. Hope anyone knows anything about this. Here is the code I'm using:

private void button1_Click(object sender, EventArgs e)
    { 

        Process process = new System.Diagnostics.Process();
        ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();

        startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
        startInfo.FileName = "cmd.exe";
        startInfo.WorkingDirectory = @"<my path>";
        startInfo.Arguments = "/k vmwindow.exe -file \"<path to vcmx file>\\Windows XP Mode.vmcx\"";
        process.StartInfo = startInfo;
        process.Start();
    }

What you can do is using Powershell. It has a native integration for Hyper V control and is easy to call from c#

You can see all HV-cmdlets here

a simple command to start your machine would be

Start-VM "Windows 8.1 Pro" -Computername HV-Host1
// etcetc
Stop-VM "Windows 8.1 Pro" -Save

So this should be something like this in C#

using (PowerShell PowerShellInstance = PowerShell.Create())
{
    PowerShellInstance.AddScript("Start-VM "Windows 8.1 Pro" -Computername HV-Host1");
}

Probably it's because of the bitness setting you compile your program with. ("Platform target" and "Prefer 32-bit" settings under the build tab of the project). 32 and 64 bit processes see different files under System32. See https://stackoverflow.com/a/950011
