convert System.Diagnostics.ProcessStartInfo from dot net 3 to 1.1

I have written a console application in visual studio 2008. The problem is that the clients doesnt have dot net framework 3.0, they only have 1.1. The app I have written simply starts a program as another user. It was smooth and easy to write in vs 2008, but the ProcessStartInfo doesnt have the password and user properties in vs 2003. What is the easiest and best way to make the same result in vs 2003. If its possible, I dont want to use the runas and sanur chell-commands.

System.Diagnostics.ProcessStartInfo myProcess = new System.Diagnostics.ProcessStartInfo("appToStart.exe", "arguments");
System.Security.SecureString password = new System.Security.SecureString();
string uspw = psw;
foreach (char c in uspw)
{
    password.AppendChar(c);
}
password.MakeReadOnly();
 
myProcess.WorkingDirectory = workingDirectory;
myProcess.UserName = user;
myProcess.Password = password;
myProcess.Domain = domain;
myProcess.UseShellExecute = false;
                
System.Diagnostics.Process.Start(myProcess);

Can you check if they have .net 2.0?
2.0 will give you what you need as well as 3~3.5.

Most everyone already has this. 3.0 and 3.5 are still unavail on most of my client machines as well.

Just looked at you pic - DOH !!!
It says you need 2.0.... sorry

under what account will your application run which you start by the following command
System.Diagnostics.Process.Start(myProcess);

the logged in user or some other user?

BillyDvD: Thanks for your being willing to help. I know, our organisation is way behind in windows client environment. They are very worried for new stuff. We got office 2002 and IE 6 :(
