process.start() throws win32Exception when credentials are given

Question

I'm trying to use Process.Start() to start a lnk file. it's fine when credentials are not provided, but throws an exception when I do. here's the sample code:

This works fine

var processStartInfo = new ProcessStartInfo
{
    FileName = @"F:\abc.lnk",
};

using (var process = new Process())
{
    process.StartInfo = processStartInfo;
    process.Start();
}

But this code throws a Win32Exception: 'The specified executable is not a valid application for this OS platform'.

var processStartInfo = new ProcessStartInfo
{
    FileName = @"F:\abc.lnk",
    UserName = userName,
    Password = securePassword,
    Domain = domain,
    UseShellExecute = false,
};

using (var process = new Process())
{
    process.StartInfo = processStartInfo;
    process.Start();
}

My OS is 32bit and the program is too

I'll need those credentials as the file is on a network drive.

Any help will be greatly appreciated!!

The docs say "When UseShellExecute is false, you can start only executables with the Process component", so passing it a .lnk file you should expect to fail.
